Changelog: [iOS][Internal] - Get the "move across" pointer event test passing on iOS
After implementing the "MoveAcross" pointer event test it indicated that the implementation, at least on iOS, was firing the events in an incorrect order. Extrapolating from the test's expectations all the events related to entering/leaving/ect. should fire before the down/move/up instead of placing those down/move/up/ect. between the leave and enter events.

Summary:
We want to fix the order of execution of layout, layout effects and passive effects in React Native, but the use of the Fabric background executor for layout complicates this (and other things).
This brings back a flag to disable this background thread to do layout synchronously in JavaScript, before the execution of layout effects and passive effects.
This is expected to regress performance on some screens, so we need to address the antipatterns in those screens before shipping this.

Summary:
Changelog: [iOS][Internal] - Rework button/buttons handling on pointer events & add a new test checking for move events on chorded mouse button presses
This is a larger diff that largely stems from implementing a new pointer event platform test about chorded mouse button presses (adapted from https://github.com/web-platform-tests/wpt/blob/master/pointerevents/pointerevent_pointermove_on_chorded_mouse_button.html). In order to implement this test I added a new method, `step`, to an async test instance to allow you to run ad-hoc assertions labeled by the async test (like it's done in the original web platform test).
Once implementing the test I also discovered my current logic for handling the `button` and `buttons` properties was insufficient so I reworked it to handle more/most cases by making the `button` property instead determined by the change in the `buttons` property. This largely works but unfortunately due to what seems to be a bug in UIKit, chorded pointer "up" events receive the wrong button mask values so it's currently impossible to get this test fully passing on iOS. I've since submitted a bug report to Apple but my hopes aren't high that it will be focused on since it's such a niche issue.

Summary:
Changelog: [iOS][Internal] - Fix ghost pointer leave/out events firing due to view recycling on iOS
While implementing the properties on the PointerEvent object on iOS I noticed that in certain specific scenarios I was seeing pointerLeave events being fired seemingly without corresponding pointerEvent events and even more strangely, when the pointer wasn't even close to the view in question.
After a lot of research I discovered that this was caused by an incompatibility between my strategy of keeping track/identifying views which are being hovered and RN's handling of creating/deleting views on iOS. See on iOS RN has the `RCTComponentViewRegistry` class which manages the creation & deletion of UIViews and adds an optimization of recycling views instead of outright deleting them.
This is causing issues with my tracking of which views are hovered because I compare the view's object references which, while accurate towards confirming equality of an underlying UIView — isn't accurate in confirming the equality of views from react's perspective.
This diff addresses this issue by adding a simple wrapper class that can be used around the UIViews which stores the view's react ID at initialization time ensuring it doesn't get updated even if the underlying view's react id is. As an additional precaution the wrapper class will also not return the view it's wrapping if their react tags do not match.

Summary:
Changelog: [iOS][Internal] - Add isPrimary property implementation to the PointerEvent object
This diff adds the `isPrimary` property to the PointerEvent object iOS implementation. In addition this adds a related change where we "reserve" the 0 touch identifier for mouse events and the 1 identifier for apple pencil events. This is an easy way to ensure that these pointers are always consistent no matter what happens. Since mouse & pencil pointers should always be considered the primary pointer, that allows us to focus the more advanced primary pointer differentiation purely on touch events.
The logic for this touch event primary pointer differentiation is essentially setting the first touch it recieves as a primary pointer, setting it on touch registration, and sets all subsequent touchs (while the first touch is down) as not the primary pointers. When that primary pointer is lifted, the class property keeping track of the primary pointer is reset and then the **next** pointer (secondary pointers which had already started before the previous primary pointer was lifted are not "upgraded" to primary) is marked as primary. A new platform test is also included in this diff in order to verify the aforementioned behavior.

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.

# Context
ScrollView sticky headers rely on this bit of code to work:
```
AnimatedImplementation.attachNativeEvent(
this._scrollViewRef,
'onScroll',
[{nativeEvent: {contentOffset: {y: this._scrollAnimatedValue}}}],
);
```
What this code means:
When the ScrollView host component receives the "onScroll" event, assign event.nativeEvent.contentOffSet.y to the this._scrollAnimatedValue AnimatedValue.
How this subscription mechanism is set up:
NativeAnimatedTurboModule subscribes to events dispatched by RCTEventDispatcher sendEvent. Then, whenever RCTEventEmitter sendEvent executes, NativeAnimatedTurboModule also updates the AnimatedValue for that event.
# Problem
Previously, in bridgeless, we started dispatching RCTScrollView via the RCTEventDispatcher sendEvent to update the AnimatedValue for ScrollView. This meant that we started dispatching the onScroll event to JavaScript via RCTEventEmitter.receiveEvent JSModule, which isn't supported in the Fabric renderer.
With this diff, we dialed back that solution. Instead of (1) notifying NativeAnimatedTurboModule and (2) sending the onScroll event to JavaScript, we're only doing (1) (i.e: notifying NativeAnimatedTurboModule).
