Summary:
The RootView being managed by Fabric should have an id of View.NO_ID when it is "handed over" to RN. This is true for Fabric and non-Fabric
and setting a custom id on the ReactRootView has never been supported. I'm temporarily (?) adding an additional check earlier and into ReactRootView to hopefully
catch any of these issues early.

Summary:
In some cases, onMeasure/onLayout are called on the RootView before `startSurface` in Fabric has been able to set surfaceId on the RootView.
With the new SurfaceMountingManager, this causes a crash because we need a valid surfaceId to perform an operation. Before the SurfaceMountingManager refactor, a surfaceId of 0 would be passed to `mBinding.setConstraints` in the FabricUIManager, and setConstraints in C++ noops if there's an invalid surfaceId.
For now, FabricUIManager will also fail silently if the surfaceId is invalid when updateRootLayoutSpecs is called, just to be conservative and to be consistent with previous behavior. This will be upgraded to a hard-crash in the future.

Summary:
The root cause of this bug is a race condition between the onMeasure method and setupReactContext.
ReactInstanceManager.attachRootView() method is responsible of the initialization of ReactRootViews and it is invoked by ReactRootView.onMeasure() method in the UIThread
Important initialization steps:
1. Clear the Id of the ReactRootView
2. Add the ReactRootView to the mAttachedReactRoots
3. Call StartSurface (if the bridge has been initialized)
Sometimes, when this method is invoked for the first time, the bridge is not initialized, in those cases we delay the start of the surface.
Once the bridge is initialized, StartSurface is called by the setupReactContext() running in the NativeModuleThread.
Since onMeasure can be called multiple times, it is possible that we call "StartSurface" twice for the same ReactRootView, causing the bug reported on T78832286.
This diff adds an extra check to prevent calling "StartSurface" twice. The fix is done using an AtomicInteger comparison and it is gated by the flag "enableStartSurfaceRaceConditionFix". Once we verify this works fine in production we will clean up the code, remove the flags and maybe revisit the API of ReactRoot.

Summary:
In D23640968 (https://github.com/facebook/react-native/commit/78b42d7fb7180102c1e8ec917dcccd2d9d4076db) I introduced a mechanism to update offsetX/offsetY whenever onMeasure/onLayout were called, to ensure that `measureInWindow` had the correct metrics and would work properly.
However, now `uiManager.updateRootLayoutSpecs` gets spammed and is called too often. For example, whenever a TextInput is focused/blurred, `uiManager.updateRootLayoutSpecs` may be called 5+ times even though
the measure specs/offsets may only change once.
Thus, we just compare with previous values before calling into the UIManager. This should give us a very small perf improvement.

# Why is text laid out twice in Fabric?
Layout constraints (min and max size) change during startup of Fabric surface.
1. `Scheduler::startSurface` is called with max size being {inf, inf}.
2. `Scheduler::constraintSurfaceLayout` is called with max size equal to viewport.
These are two operations that don't happen one after the other and on Android, CompleteRoot is called from JS before second operation is called. This triggers layout with max size {inf, inf} and later when second operation is called. Layout happens again now with correct size.
# Fix
Make sure `Scheduler::startSurface` is called with proper values and not {inf, inf}.

Summary:
In the past, in Fabric (Android), we never called stopSurface. Ever! This is bad for memory and can cause other issues, so... let's not do that.
Instead, when the ReactRootView is being torn down, we check the View ID to see if it's a Fabric RootView, and if it is, we call Fabric's stopSurface method.
Fabric stopSurface only has impact on (1) Fabric mount instructions being executed after that point and (2) tells JS to stop running the surface, on the JS thread, asynchronously.
Anecdotally it looks like all the MountItems involved in deleting and removing views from the hierarchy are executed before stopSurface is called.

Summary:
ReactRootView currently caches the last seen DisplayMetrics so we can compare them against the current values in DisplayMetricsHolder to determine if the screen dimensions have changed. (If they have changed, we emit an event to notify JS of the new dimensions).
However, ReactRootView initializes these member variables with empty DisplayMetrics, which means that the first time we check against them in onGlobalLayout, we will *always* emit an event to JS.
This seems reasonable if you only have one ReactRootView, but if you create a new RRV for each RN screen in your app, then you're going to get updated dimensions on each navigation event, even though the screen dimensions have probably not changed.
In this diff, I'm no longer storing the DisplayMetrics in ReactRootView at all, but instead am using temporary variables to check the new DisplayMetrics values against the old.

This diff does a few different things:
1. Unify iOS and Android by removing the `#ifndef` for Android so that we call `startSurface` for both
2. Pass through the JS module name on Android so that this actually works (it currently passes in an empty string)
3. Remove the call to `ReactRootView.runApplication` for Fabric so that we don't end up doing this twice
4. Copy over some logic that we need from `ReactRootView.runApplication` (make sure that root layout specs get updated, and that content appeared gets logged)

Summary:
This pull request enhances the Keyboard API event emitter for Android upon `keyboardDidHide` by returning a `KeyboardEvent` with a meaningful `endCoordinates` property (instead of emitting a null as of current implementation). This change standardizes the `keyboardDidHide` keyboard event emission across both iOS and Android, which makes it easier for developers to use the API.
In particular, the semantics of `endCoordinates` emitted during the `keyboardDidHide` event on Android will match nicely with semantics of the same event emitted on iOS:
- `screenY` will be height of the screen, as that the keyboard has collapsed to the bottom of the screen
- `screenX` will be 0, as the keyboard will always be flush to the sides of the screen
- `height` will be 0, as the keyboard has fully collapsed
- `width` will be the width of the screen, as the keyboard will always extend to the width of the screen
Also, the flowtypes for `KeyboardEvent` have been further improved and are more explicit to better highlight the different object shapes (see `IOSKeyboardEvent` and `AndroidKeyboardEvent`) depending on the platform.

Summary:
This diff ensures the method scheduler.constraintSurfaceLayout is executed before the JS run application start.
This is necessary to properly set the pointScaleFactor for the Root before running JS.
This is a workaround to fix a bug when the pointScaleFactor changes over time for the rootShadowNode. The bug is easily reproducible when rendering the "fabric" indicator on Fabric screens. During the first render of a Fabric screen this method was called before "JS run application" starts, and the Fabric indicator was render correctly.
Beacuse of timing of measure APIS, the second time a Fabric screen is rendered the method is called after the "JS run application process started", as a consecuence the Fabric indicator is not rendered correctlly (the pointScaleFactor is incorrectly assigned into the layout metrics of the Fabric indicator text).
We still need to analyze why the pointScaleFactor is not correctly assigned when it is set after the "JS run application process started", but this will be part of another diff.

Summary:
Instead of using measure specs to set certain yoga properties on the root node (like max width, auto width, specific width), use yoga's calculateLayout(width, height) instead. The measure specs will be stored in the shadow node. This allows us to remove duplicated code that processes the measure specs and allows us to remove other logic like the enableLayoutCalculation() method.
This diff also removes MeasureSpecProvider. MeasureSpecProvider was originally introduced to pass previously measured view measure specs to the initial creation of the root shadow node, but it turns out that this is unnecessary. We can update the root layout specs from the root view instead.

Summary:
We are writing a native navigation library. When there are more than a dozen `ReactRootView` in the application, the application will be very stuck. It doesn't improve much, even if we remove the invisible ReactRootView from the View hierarchy temporarily.
After debugging, we found that we were not able to remove `OnGlobalLayoutListener` in `onDetachedFromWindow` because this listener was added twice. One is in `onAttachedToWindow` and the other is in `attachToReactInstanceManager`.
We added the following code by inheriting ReactRootView.
```java
Override
protected void onAttachedToWindow() {
try {
Method method = ReactRootView.class.getDeclaredMethod("getCustomGlobalLayoutListener");
method.setAccessible(true);
// remove duplicated GlobalLayoutListener
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
getViewTreeObserver().removeOnGlobalLayoutListener((ViewTreeObserver.OnGlobalLayoutListener) method.invoke(this));
} else {
getViewTreeObserver().removeGlobalOnLayoutListener((ViewTreeObserver.OnGlobalLayoutListener) method.invoke(this));
}
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
super.onAttachedToWindow();
}
```
It turns out that there is no pressure even if opening hundreds of pages that contain ReactRootView (remove ReactRootView from the View hierarchy temporarily in the invisible pages).

Summary:
It works great on iOS, and mostly works on Android, and is now OTA'able as part of the screen config! Haven't done template view yet. One remaining issue:
Layout is borked on Android. I'm guessing the issue has to do with the timing of setting the constraints in `updateRootLayoutSpecs` and calling `mBinding.startSurface` which actually builds the shadow tree. If I try to call `updateRootLayoutSpecs` earlier, it just crashes immediately. Here's the layout it spits out, which clearly has -440 for the x of 420006, which is the RCTText component, causing it to get cut off on the left of the screen:
```
