Summary:
## Context
```isRootViewVisible``` doesn't work as expected for non-Venice: when enter Marketplace tab, ```isRootViewVisible``` should returns true with Marketplace tab's rootViewTag, but it returns false.
## Root cause
```rootViewTag``` is added to "mVisibleRootTags" in "FbReactRootVisibilityTracker" when ```BaseFbReactFragment.onViewDidAppear()``` gets called, but ```BaseFbReactFragment.onViewDidAppear()``` is called earlier than when the ```rootViewTag``` is set.
## Fix
Move setRootViewTag to earlier when RootView is created instead of in startSurface or mounting.

Pull Request resolved: https://github.com/facebook/react-native/pull/34435
Currently we expose native code (.h, .cpp) inside the src/main/java folder.
This is making impossible for users on New Architecture to open the project
inside Android Studio.
The problem is that the src/main/java is reserved to Java/Kotlin sources only.
AGP 7.2 also removed support for mixed source roots:
https://developer.android.com/studio/releases/gradle-plugin#duplicate-content-roots
This is essentially forcing users to write Java code without any autocompletion
as all the React Native Java classes are considered C++ files.
I'm addressing this issue folder by folder by moving them
from ReactAndroid/src/main/java/com/facebook/... to ReactAndroid/src/main/jni/react/...
This is the diff for fabricjni

Summary:
This Pull Request aims at removing the making of reactnativeutilsjni as it is built from the same sources as reactnativejni. It also replaces references to reactnativeutilsjni with reactnativejni.
This should get rid of `reactnativeutilsjni.so` while reusing `reactnativejni.so` in it's place. This should give us some size improvements in the finally built apk.

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:
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:
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).

Summary:
There is a very small volume of production errors caused by a View that is already in the hierarchy being added to the hierarchy again; this results in a crash on the Android platform layer.
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.
