Summary:
Android's onAnimationEnd callback is lossy and ocasionally just does not fire. However the LayoutAnimationController maintains a sparse array of animations (with Strong View refs) that is only cleaned when the onAnimationEnd callback is invoked. This results in a leak of Android View objects over time.
To avoid this, the Strong View refs are migrated to WeakReference's and the associated sparse array is cleaned of any invalid layout animations in response to the reset() call.
This closes two leaks:
1. Unbound growth in LayoutAnimationController::mLayoutHandlers
2. Pinning View objects into memory as the sole remaining GC root
## Changelog:
1. Made OpacityAnimation and PositionAndSizeAnimation classes hold weak refs to views only
2. Added a method to LayoutHandlingAnimation to surface if their view ref is gone
3. Added cleanup for Animation with bad view refs

[ANDROID] [Fixed]- Fixes memory leak

This diff introduces annotations into the ios codegen config!
## Before
In the new architecture, people can declare module/component codegen config in [package.json](https://reactnative.dev/docs/the-new-architecture/using-codegen#configuring-codegen)
This config contains the following maps:
- modulesConformingToProtocol
- modulesProvider
- componentProvider
```
"codegenConfig": {
"name": "HelloWorldSampleModule",
"type": "all",
"jsSrcsDir": "specs",
"android": {
"javaPackageName": "com.helloworld"
},
"ios": {
"modulesConformingToProtocol": {
"RCTImageURLLoader": [
"RCTHelloWorldImageURLLoader"
],
"RCTURLRequestHandler": [
"RCTHelloWorldURLRequestHandler"
],
"RCTImageDataDecoder": [
"RCTHelloWorldImageDataDecoder"

},
"modulesProvider": {
"HelloWorldImageURLLoader": "RCTHelloWorldImageURLLoader",
"HelloWorldURLRequestHandler": "RCTHelloWorldURLRequestHandler",
"HelloWorldImageDataDecoder": "RCTHelloWorldImageDataDecoder"
},
"componentProvider": {
"FooComponent": "RCTFooComponentClass"
}
}
```
## After
This information is a little bit easier to understand if we group it by module/component (into **annotations**):
(that's what this diff does!)
```
"codegenConfig": {
"name": "HelloWorldSampleModule",
"type": "all",
"jsSrcsDir": "specs",
"android": {
"javaPackageName": "com.helloworld"
},
"ios": {
"modules": {
"HelloWorldImageURLLoader": {
"conformsToProtocols": ["RCTImageURLLoader"],
"className": "RCTHelloWorldImageURLLoader"
},
"HelloWorldURLRequestHandler": {
"conformsToProtocols": ["RCTURLRequestHandler"],

"conformsToProtocols": ["RCTImageDataDecoder"],
"className": "RCTHelloWorldImageDataDecoder"
}
},
"components": {
"FooComponent": {
"className": "RCTFooComponent"

},
}
```
## Migration
The old way is still supported (for now). We will deprecate it soon, and eventually remove it from react native!

This PR (https://github.com/facebook/react-native/pull/48182) introduced skipping hidden folders during Codegen generation.
However, when using pnpm, all files are stored in the `.pnpm` folder (see explanation here: https://pnpm.io/symlinked-node-modules-structure).
As a result, some libraries that support the new architecture but lack the `ios.codegenConfig.componentProvider` field - like [FlashList](https://github.com/Shopify/flash-list/blob/main/package.json) - will be skipped during Codegen generation.
This PR explicitly includes `.pnpm` to prevent this issue.

(because MutationObserver isn't a public API yet)
## Context
`MutationObserver` is a [JavaScript API](https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver) used to report mutations in the DOM tree. The mutations available on Web are: changing children, changing attributes and changing text. In React Native, only changing children is supported.
Mutation detection needs to happen synchronously when mutations happen (in ShadowTree commits) and the notification is dispatched as a microtask in JS, which means we can only report mutations happening in JavaScript.
There's an assumption that only React (in JS) can change the structure of the tree in Fabric, so we implemented `MutationObserver` considering this assummption.
Unfortunately, while the assumption is correct (we can only mutate children from React) the implementation didn't take into account that commit hooks were triggered from multiple threads, even if the structure doesn't change (e.g.: with Fabric state updates). In this case, we do the checks but we never dispatch the notifications. This can cause crashes (see T217617393) if we try to check for mutations from the main thread while we add new observers in the JS thread (because that logic wasn't thread safe).
This fixes that crash by, in MutationObserver, not only preventing notifications from commits not coming from React, but also preventing the determination altogether.
In order to do this, this modifies the signature of the commit hooks to also pass the commit options, and adds a new field in the commit options with the source of the commit (for now, just "React" or "Unknown").
In `MutationObserver`, before accessing the data structures of the observer, we check if the commit is coming from React, and return early otherwise.

The feature flag system currently logs an error when trying to access common feature flags (flags accessible from everywhere but defined in native) from JS if the native module isn't available.
This forces a pattern in code to check if the module is available before accessing certain feature flags, to avoid showing that error to users in the legacy architecture.
This removes the need for that pattern by adding the check in the feature flag infra itself. If TM infra isn't available, we return default values and don't log the error.

RN legacy arch, and web, will clip inline content which appears after elipsized text. This is the correct behavior, compared to new arch, which will put it in a random place depending on the platform.
`line-clamp`: https://jsfiddle.net/7xgdke1b/
`text-overflow`: https://jsfiddle.net/7xgdke1b/2/
Fabric renderer does not, funnily enough, having an `isClipped` field on `TextMeasurement::Attachment` that is never used.
This change propagates state for whether an attachment is beyond elipsized area to this measurement, then when we see it, we set empty layout results with `DisplayType::None` so that we don't create native views. We don't layout child views either, but this seems to work out okay, even when removing and re-adding `numberOfLines`.

When using `ReactScrollView` or `ReactHorizontalScrollView` Views with `removeClippedSubviews` keyboard navigation didn't work.
This is because keyboard navigation relies on Android's View hierarchy to find the next focusable element. With `removeClippedSubviews` the next View might've been removed from the hierarchy.
With this change we delegate the job of figuring out the next focusable element to the Shadow Tree, which will always contain layout information of the next element of the ScrollView.

We previously fixed Differentiator generating an incorrect parentTag (https://github.com/facebook/react-native/pull/48055), but this can lead to crashes in Android UI due to reordering that happens in the Android mounting layer. While we have an experiment to disable this reordering (https://github.com/facebook/react-native/pull/46702) this currently has a negative performance impact which needs to be addressed.
As a mitigation, we can make the lookup of parentTag's ViewManager state nullable. We only require this to support `needsCustomLayoutForChildren`, which is not commonly used, and seems acceptable to drop in this scenario.

This change automates updating App's Info.plist with the new `RCTNewArchEnabled` boolean entry. The value depends on how the pod install is set up. In this way, we maintain the previous UX to enable/disable the New Arch.
## Context
The RCT_NEW_ARCH_ENABLE flag is a compile time flag we used for almost two years to configure the iOS apps and to determine whether the app should build with the New Arch or not.
However, given that we are looking into prebuilding React Native, we have to get rid of all the compilation flags, because they would require us to prebuild a combinatorial number of artifacts for react native. For example:
- New Arch / Hermes
- Old Arch / Hermes
- New Arch / JSC
- Old Arch / JSC
- ...
## Backward compatibility
We are going to keep adding the RCT_NEW_ARCH_ENABLED flag in all the dependencies, through the cocoapods inrastructure, so libraries, which are not prebuilt, will be build for the right architecture by the app itself.
