Summary:
Some custom logic is applied to workaround a platform bug where velocity may be incorrect on Android P. [The bug in question](https://issuetracker.google.com/issues/112385925) appears to have been fixed before Android `Q` was released, so we shouldn't *need* to apply the workaround on other versions.
As described in https://github.com/facebook/react-native/issues/34226 the workaround can adversely affect certain scroll behaviors, which can easily be reproduced when you briefly scroll one direction then quickly fling the opposite direction (see the video in the linked ticket).
This PR changes the workaround to *only* be applied on Android P, in order to avoid causing weird scroll behavior on versions that are not actually affected by the bug the workaround is working around.
## Changelog
```
[Android] [Fixed] - Fix occasionally incorrect ScrollView fling behavior
```
Pull Request resolved: https://github.com/facebook/react-native/pull/34233
Test Plan:
- Repro the strange fling behavior in the current version (See video attached in https://github.com/facebook/react-native/issues/34226)
- Verify that the string fling behavior is fixed with this patch
- Verify that fling behavior still works as expected on Android versions affected by the [original bug](https://issuetracker.google.com/issues/112385925), and those immediately following it (to verify that the bug being worked around was, in fact, fixed as expected).

Summary:
Calculation of TransformedFrames was a method introduced by D37994809 (https://github.com/facebook/react-native/commit/64528e5faa445907b8287b412c344f30c20fca61) to fix rendering of inverted flat lists.
We found that this operation is crashing in fb4a causing the UBN T127619309
This diff creates a feature flag to disable the calculation of TransformedFrames in Layoutable ShadowNodes. **The goal of this diff is to revert the behavior introduced by D37994809 (https://github.com/facebook/react-native/commit/64528e5faa445907b8287b412c344f30c20fca61)**
The featureFlag is disabled in fb4a and enabled in react AR (because ReactAr apps relies on the calculation of TransformedFrames and these apps are not affected)
The root cause of the bug will be fixed by D38280674 (which still requires more testing and investigation)

Summary:
While I was working on rewriting `react-native-slider` to Fabric I found a weird bug that prevented the slider to be set as disabled (to be exact: call the method `slider.setEnabled(false)`. As it turned out the `accessibilityState` (with value: `accessibilityState={{disabled: true}}` prop occurred after the `enabled={false}` prop that I was passing to the slider, which lead to both of this props overwrite each other.
Handling of `accessibilityState` props inside view leads to always overwriting the enabled prop to true (even if we explicitly set it to `{disabled: false}`.
Workaround for this was to reorder the props, so that the `accesibilityState` occur before `disabled`, but I think it's better to not set `view.setEnabled(true)` if we are passing a disabled property.

Summary:
Fixes https://github.com/facebook/react-native/issues/34120
The new React Native architecture doesn't check `needsCustomLayoutForChildren` so it wrongly positions native views on Android. In https://github.com/facebook/react-native/issues/34120 there are videos comparing the positioning of a native action view in the old and the new architecture.
This PR passes the parent tag to the `updateLayout` method of the `SurfaceMountingManager`. The `SurfaceMountingManager` calls `needsCustomLayoutForChildren` on the parent view manager (copied the code from the `NativeViewHierarchyManager` in the old architecture).
**NOTE** - I wasn't sure where to get the parent shadow view from so I've put in my best guesses where I could and left it as `{}` otherwise.

Summary:
Changelog: [Android][Fixed] - Fix such that when the scrollviews call `onChildStartedNativeGesture`, they appropriately call `onChildEndedNativeGesture` to unlock the native gesture such that `JSTouchDispatcher` or `JSPointerDispatcher` will continue to emit events.
### How did we find this issue?
As React Native is adding pointer event support for different input types, we noticed after pressing and dragging on a ScrollView, hover events would not fire.
### Why was this not an issue before?
This was always an issue -- it was just that `JSTouchDispatcher` worked its way around it by explicitly setting `mChildIsHandlingNativeGesture = false` on a `ACTION_DOWN` event, [code pointer](https://github.com/facebook/react-native/blob/main/ReactAndroid/src/main/java/com/facebook/react/uimanager/JSTouchDispatcher.java#L76). Similarly, `JSPointerDispatcher` [copied this logic](https://github.com/facebook/react-native/blob/main/ReactAndroid/src/main/java/com/facebook/react/uimanager/JSPointerDispatcher.java#L106).
With new hover support in `JSPointerDispatcher` no similar workaround was put in (or even a good place to insert).
### What's next?
* As a follow-up, we should look at removing this workaround (at least for `JSPointerDispatcher`)
* By searching for usages of where we `notifyNativeGestureStarted`, it looks like `ReactDrawerLayout` and `ReactSwipeRefreshLayout` both do and don't call the symmetric `notifyNativeGestureEnded`. This will likely be an issue in the future (or maybe if we remove the workaround)

Summary:
Internal tests are indicating that there's an OOM that happens during the RemoveDeleteTree worker loop while trying to expand the size of the tag stack.
In practice during manual testing I was not able to get the capacity beyond 40, but for deletions of very large trees, it's easy to imagine the size of the stack growing to at least the number of nodes in the tree being deleted. To mitigate this, we relax our requirements around the order in which onViewStateDeleted can be called and call it top-down instead of bottom up to maintain a smaller stack (see comments for more details).

We detect and attempt to silently recover from this case, while logging and collecting more diagnostics. This will still crash in debug mode.
It is unclear what layer this error is coming from: it could be an issue with the C++ differ (ordering, or something more tricky); that is unlikely but there are few other hypotheses at the moment.

Summary:
Due to the way we're dispatching queued MountItems on Android, we could be doing nothing on the UI thread for up to 15.99...ms before the start of the next frame, resulting in a delayed paint of up to 1 full (16ms) frame.
The delay is totally random and depends only on when the work is scheduled.
The tl;dr is that currently all MountItems are dispatched starting only at the /beginning/ of a UI frame. If we schedule work at FrameStart+0.000001ms, it will not be operated on until the start of the next frame, 16ms later. So the "wasted" time could be anywhere from 0 to ~16ms, but will result in at least 1 wasted frame regardless.
The fix is fairly trivial: start working on large buffered work as soon as we schedule it.

Summary:
Instead of directly scheduling a Runnable on the UI thread, use a GuardedFrameCallback which (1) guards against exceptions thrown on the UI thread (in this case, errors in deferred remove/delete work really should not disrupt the UI at all or cause user-visible crashes) (2) allows us to split work across multiple frames if necessary (3) is more consistent with how we schedule other work on Android.
The only functionality change is that we might split work across multiple callbacks, in the case of tearing down a particularly large tree.

Summary:
TL;DR: For applications using JS navigation, save 50-95% of CPU during mounting phase in N>2 navigations that replace ~most of screen.
During investigation of performance on the UI thread of React Native applications, I noticed that the /initial/ render of an screen for an application using JS navigation is /mostly/ consumed (on the UI thread) by tearing-down the previous View hierarchy. In one 185ms segment on the UI thread in production, 95% of the CPU time was Remove/Delete instructions and only 5% of CPU time was consumed by actually displaying the new hierarchy (this is specific to Android and also assumes that View Preallocation is being used, so post-commit work consists of Insert and UpdateLayout mutations primarily).
There are /some/ cases where the C++ differ knows that we are deleting an entire subtree and therefore we could communicate this to the mounting layer. All that matters is that these Views are removed from the View hierarchy immediately; and secondarily that their memory is cleaned up ASAP, but that doesn't need to happen immediately.
Some additional constraints and notes:
1) As noted in the comments, we cannot simply stop producing Remove and Delete instructions. We need to produce /both/ the new RemoveDeleteTree instruction, /and/ produce all the Remove/Delete instructions, primarily because LayoutAnimations relies heavily on these Remove/Delete instructions and certain things would break if we removed those instructions entirely. However, we can mark those Remove/Delete instructions as redundant, process them only in LayoutAnimations, and not send them to the Android mounting layer.
2) We want to make sure that View Recycling is not impacted. Since Android cannot take advantage of View Recycling until /after/ the second major render (preallocation of views will happen before any views are recycled), this doesn't impact View Recycling and we'll make sure Views are recycled whenever they are deleted.
Thus, we do two things:
1) Introduce a new RemoveDeleteTree operation that can delete an entire subtree recursively as part of one operation. This allows us to avoid serializing hundreds or thousands of instructions and prevents JNI traffic.
2) Besides removing the topmost View from the View hierarchy, and ensuring it's not drawn, the full teardown and recycling of the tree can happen /after/ the paint.
In some flows with JS navigation this saves us 95% of CPU during the mount phase. In the general case it is probably closer to 25-50% of CPU time that is saved and/or deferred.

Summary:
The current implementation of **getDefaultJSExecutorFactory** relies solely on try catch to load the correct .so file for jsc or hermes based on the project configuration.
Relying solely on try catch block and loading jsc even when project is using hermes can lead to launch time crashes especially in monorepo architectures and hybrid apps using both native android and react native.
So we can make use of an additional **ReactInstanceManager :: setJsEngineAsHermes** method that accepts a Boolean argument from the host app while building ReactInstanceManager which can tell which library to load at startup in **ReactInstanceManagerBuilder** which will now have an enhanced getDefaultJSExecutorFactory method that will combine the old logic with the new one to load the dso files.
The code snippet in **ReactInstanceManager** for adding a new setter method:
```
/**
* Sets the jsEngine as JSC or HERMES as per the setJsEngineAsHermes call
* Uses the enum {link JSInterpreter}
* param jsEngine
*/
private void setJSEngine(JSInterpreter jsEngine){
this.jsEngine = jsEngine;
}
/**
* Utility setter to set the required JSEngine as HERMES or JSC
* Defaults to OLD_LOGIC if not called by the host app
* param hermesEnabled
* hermesEnabled = true sets the JS Engine as HERMES and JSC otherwise
*/
public ReactInstanceManagerBuilder setJsEngineAsHermes(boolean hermesEnabled){
if(hermesEnabled){
setJSEngine(JSInterpreter.HERMES);
}
else{
setJSEngine(JSInterpreter.JSC);
}
return this;
}
```
The code snippet for the new logic in **ReactInstanceManagerBuilder**:
1) Setting up the new logic:
Adding a new enum class :
```
public enum JSInterpreter {
OLD_LOGIC,
JSC,
HERMES
}
```
A setter getting boolean value telling whether to use hermes or not and calling a private setter to update the enum variable.
```
/**
* Sets the jsEngine as JSC or HERMES as per the setJsEngineAsHermes call
* Uses the enum {link JSInterpreter}
* param jsEngine
*/
private void setJSEngine(JSInterpreter jsEngine){
this.jsEngine = jsEngine;
}
/**
* Utility setter to set the required JSEngine as HERMES or JSC
* Defaults to OLD_LOGIC if not called by the host app
* param hermesEnabled
* hermesEnabled = true sets the JS Engine as HERMES and JSC otherwise
*/
public ReactInstanceManagerBuilder setJsEngineAsHermes(boolean hermesEnabled){
if(hermesEnabled){
setJSEngine(JSInterpreter.HERMES);
}
else{
setJSEngine(JSInterpreter.JSC);
}
return this;
}
```
2) Modifying the getDefaultJSExecutorFactory method to incorporate the new logic with the old one:
```
private JavaScriptExecutorFactory getDefaultJSExecutorFactory(
String appName, String deviceName, Context applicationContext) {
// Relying solely on try catch block and loading jsc even when
// project is using hermes can lead to launch-time crashes especially in
// monorepo architectures and hybrid apps using both native android
// and react native.
// So we can use the value of enableHermes received by the constructor
// to decide which library to load at launch
// if nothing is specified, use old loading method
// else load the required engine
if (jsEngine == JSInterpreter.OLD_LOGIC) {
try {
// If JSC is included, use it as normal
initializeSoLoaderIfNecessary(applicationContext);
JSCExecutor.loadLibrary();
return new JSCExecutorFactory(appName, deviceName);
} catch (UnsatisfiedLinkError jscE) {
if (jscE.getMessage().contains("__cxa_bad_typeid")) {
throw jscE;
}
HermesExecutor.loadLibrary();
return new HermesExecutorFactory();
}
} else if (jsEngine == JSInterpreter.HERMES) {
HermesExecutor.loadLibrary();
return new HermesExecutorFactory();
} else {
JSCExecutor.loadLibrary();
return new JSCExecutorFactory(appName, deviceName);
}
}
```
### **Suggested changes in any Android App's MainApplication that extends ReactApplication to take advantage of this fix**
```
builder = ReactInstanceManager.builder()
.setApplication(this)
.setJsEngineAsHermes(BuildConfig.HERMES_ENABLED)
.setBundleAssetName("index.android.bundle")
.setJSMainModulePath("index")
```
where HERMES_ENABLED is a buildConfigField based on the enableHermes flag in build.gradle:
`def enableHermes = project.ext.react.get("enableHermes", true)
`
and then
```
defaultConfig{
if(enableHermes) {
buildConfigField("boolean", "HERMES_ENABLED", "true")
}
else{
buildConfigField("boolean", "HERMES_ENABLED", "false")
}
}
```
Our app was facing a similar issue as listed in this list: **https://github.com/facebook/react-native/issues?q=is%3Aissue+is%3Aopen+DSO**. Which was react-native trying to load jsc even when our project used hermes when a debug build was deployed on a device using android studio play button.
This change can possibly solve many of the issues listed in the list as it solved ours.

Test Plan:
The testing for this change might be tricky but can be done by following the reproduction steps in the issues related to DSO loading here: https://github.com/facebook/react-native/issues?q=is%3Aissue+is%3Aopen+DSO
Generally, the app will not crash anymore on deploying debug using android studio if we are removing libjsc and its related libraries in **packagingOptions** in build.gradle and using hermes in the project.
It can be like:
```
packagingOptions {
if (enableHermes) {
exclude "**/libjsc*.so"
}
}
```

Summary:
Changelog: [Internal] Fixing a recent optimization to prevent event dispatches for events that are not listened for. An incorrect hitpath was passed in for `leave` events.
Refactored the PointerEvent optimization such that `filterByShouldDispatch` determines what views should dispatch a PointerEvent, and `dispatchEventForViewTargets` to actually dispatch them. We are separating this because the order of dispatch differs between `enter` and `leave` events.

Summary:
We need to check that the animated node exists prior to executing the animation. The native animated node lifecycle is not synced with Fabric and nodes are frequently destroyed and re-created on rerenders. Therefore, there is a possibility that the the animated node does not exist when the native event is dispatched, in particular with native call batching.

[Internal] - Make NativeAnimatedNodesManager.getNodeById public

Summary:
ThemedReactContext should be what is stored as the context on all RN views, but some legacy components use other things like an Activity.

Summary:
This PR is a follow up for the contributing content move on the website:
* https://github.com/facebook/react-native-website/pull/3120
It replaces most of the CONTRIBUTING file content with a reference to the contributing overview page on the website, which has been based off the content of this file.
Additionally I have searched thought the code for the wiki links and replaces theme with the correct website links. There was an instance where comment was referring to an old and removed a while ago wiki page, so I just get rid of this link.
## Changelog
[Internal] [Chore] - Update CONTRIBUTING.md, replace wiki links
