Changelog: [internal]
This replaces the use of `ShadowNode` with `ShadowNodeFamily` in the `MutationObserver` logic to prevent retaining stale subtrees of the nodes being observed.
It refactors some existing logic so we don't need to keep track of the shadow nodes in JS. It was only used to be able to find the node for a target after unmounted, so we could "unobserve" it, but `MutationObserver` doesn't support unobserving individual targets anyway, so we removed that use case and implemented a more general `unobserveAll` method that doesn't require the shadow nodes in the first place.

Pull Request resolved: https://github.com/facebook/react-native/pull/51089
Currently, `IntersectionObserver#observe` retains a reference to the `ShadowNode` of the view that is supplied as an argument, which is used to compute intersection whenever a shadow tree is committed.
However, the `shadowNode` includes all of child nodes and state at the time that `IntersectionObserver#observe` is called. This means that an active `IntersectionObserverEntry` will retain references to memory that would otherwise be deallocated (e.g. if children of the observed view are unmounted after `IntersectionObserver#observe` is called).
This diff refactors `IntersectionObserver` to instead retain a reference to the `ShadowNodeFamily`, which does not retain references to child nodes and still eanbles `IntersectionObserver` to compute intersections.

[General][Changed] - Fixed `IntersectionObserver#observe` to avoid retaining memory for unmounted child nodes of observed views.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51065
This adds infrastructure to let us start storing cached Android text layouts as part of a `ParagraphShadowNode`. After this, we will clear them out, and propagate them to state. Right now, the flag doesn't do much, apart from extra work.
This is done by adding `TextLayoutManagerExtended::supportsPreparedLayout()`, and `TextLayoutManager::PreparedLayout` types, to shim between platforms, then on Android, we add a `PreparedLayout`, which is for now just an Android layout, with extra field (`maxNumberOfLines`, for some reason not exposed on recent versions).
Android `TextLayoutManager` java side is split a little bit, so that we reuse all the existing logic for prepared layouts. I tried to set up the boundary, so that we don't reserialize a MapBuffer after preparation, and for simplicity, this means source of truth for attachment count, and attachment sizes, now lives on the layout. This means we need to change boundary a bit, where we are no longer able to pass in a buffer to fill from C++ side of attachment positions.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/50997
In some apps, we spend a non-trivial amount of time calling ShadowNode destructors on the UI thread.
A simple way to avoid stalling the UI thread is to move the `baseRevision_` instance to a data structure that is cleared on a background thread, so it's tree of ShadowNode shared_ptrs are released (and in most cases destroyed) on the background thread.
Rather than using std::thread, this change introduces the LowPriorityExecutor abstraction that should be supplied by host platforms. The implementation of this LowPriorityExecutor for each platform is as follows:
- iOS: uses dispatch_async to a low priority dispatch queue
- Android: uses a pthread with SCHED_OTHER and priority = 19
Moving the ShadowTreeRevision into a lambda capture and punting the lambda to the LowPriorityExecutor moves the destructor calls of the ShadowNodes to the host platform implementation of the LowPriorityExecutor.
This change is also guarded by a feature flag so we can keep an eye out for potential memory leaks.

This effectively reverts D67064488
We are trying to smash together functions, variables, virtual or non-virtual, all required by different platforms, into a single header, often using #ifdefs that are not what we want (apart from a bad editor experience, `#ifdef ANDROID` may or may not be compiled into the react-native-cxx platform, and we cannot use it for the Android platform reliably).
For Facsimile, we are going to be introducing more potential divergence, with the idea of `PreparedText`, where we can generate intermediate products as part of the layout process to be reused later. I'm planning to design that in a way which can be eventually reused across platforms, but not everywhere.
I think the best path for this is going to be to allow each platform to have their own headers, instead of the current messiness, then allow shared code (e.g. in `ParagraphShadowNode`) to pick how to interact at compile time. I added an example of this as part of `TextLayoutManagerExtended`, to customize how we act if a `TextLayoutManager` chooses not to implement `measureLines`.

With Facsimile, we are introducing some new concept of `PreparedText`, where platform TextLayoutManager which implement, can lead to additional optimizations.
`#ifdef ANDROID` is not a workable pattern for this. Apart from react-native-cxx getting hooked into it, and all of the existing bugs there, it is bad for editor environment, and hard to reason about.
This splits up `ParagraphState`, so that we can control platform specific bits more easily. We do not split `ParagraphShadowNode`, which will use concepts (e.g. `TextLayoutManagerWithPreparedText`) to control which paths it takes, based on platform capaibilities.

This forms the basis for a replacement of `TextView`.
This started off with Litho's [`RCTextView`](https://github.com/facebook/litho/blob/master/litho-rendercore-text/src/main/java/com/facebook/rendercore/text/RCTextView.java), which is a simple view, for rendering a text layout, and providing some built-in keyboard navigation and a11y support. Many changes were made to it, including:
1. Removing many parts not relevant to RN, or which will be replaced by other RN infra. E.g. we will reuse existing a11y delegates, have existing ways of creating Spannables and text layouts, inline views, etc
2. Converting to Kotlin
3. Adding back in some changes required for RN's drawing, and expected view manager APIs (e.g. overflow/clipping customization)
4. Making it target a ViewGroup instead of a View, for correct inline view support down the line
Because we rely on drawing text layout, with the same Spannable as before, most things "just work", because they are part of the layout we are drawing, generated by TextLayoutManager on the Fabric side. We don't offer much customization to what can be drawn, forcing it to have happened in the layout we are showing already.
There are quite a few bits not implemented yet. Some of these are cases, like `textAlignVertical`, were previously incorrectly implemented just at the ReactTextView layer, so Fabric layout was unaware of them. Another similar class to this is any non-default fonts which we must load. `adjustsFontSizeToFit` (stubbed out in later diff) will also need some tweaking with the new assumption we don’t want to mutate Spans/layouts set in State.
Fine grained selection support is the largest tbd.

This adds the ability to represent Fabric State sent to Java View managers as a raw JNI reference. This is used by Facsimile to tell a component to mount a layout, previously generated during measurement.
This API is consciously well hidden (in comparison to MapBuffer which is fairly public). To use it:
1. The concrete state data representation must implement a method named `getJNIReference()` that returns an fbjni ref
2. The Java view manager must cast the `StateWrapper` to an internal `ReferenceStateWrapper` type, not exposed outside of React Native internals

Pull Request resolved: https://github.com/facebook/react-native/pull/50753
Runtime Shadow Node Reference Updates (RSNRU) is currently implemented through the clone method which on each internal clone updates the runtime reference to point to the new clone. This guarantees that the runtime reference always points at the latest revision of the shadow node.
This came with the constraint that RSNRU could only run from one thread at all times, otherwise the React renderer state (current fiber tree) would end up being corrupted by receiving reference updates from multiple threads cloning shadow nodes.
This change moves the reference update step to the locked scope of the commit phase. Since the runtime is blocking on the commit and the scope is locked, it is safe and correct to update the runtime references with the latest revision of the shadow node after running state progression and layout.
By moving the reference update to the commit, we can support shadow node syncing from any thread since the actual runtime references are now executing at a safe time and the renderer state will stay valid at all times.
This change is gated behind the `updateRuntimeShadowNodeReferencesOnCommit` feature flag, which enabled shadow node syncing from any thread and reference updates only during the commit.

Storing the runtime reference for a shadow node and updating the runtime reference to point at a specific shadow node should be separated so that these actions can be done at different moments in time.
We want to keep a reference to the runtime reference of a shadow node for all revisions cloned internally (not triggered by the React renderer, e.g. on layout or shadow node state updates).
We also want to support updating that runtime reference to point at a specific shadow node revision, ideally the one that will end up being used to mount the host component.

On iOS, by default, every EditText accepts DragEvent and will automatically focus themselves to accept these data. In some rare cases, it might not be desirable to allow data from arbitrary drag and drop events to be pasted into a text input.
This change adds a new prop `acceptDragAndDropTypes` to do exactly that: reject drag and drop events by telling the system to ignore certain types of drag data and, by proxy, disabling behavior that automatically focuses the text input.
The prop accepts a list of [Uniform Type Identifiers](https://developer.apple.com/documentation/uniformtypeidentifiers) that iOS supports. It's important to note that these are *not* MIME types. A MIME type would be something like `text/plain` but the equivalent for iOS is `public.plain-text`.
It's important to note that this is an experimental prop, as is evident by the `experimental_` prefix on the JS side. Its signature could change before the prop has fully matured, use at your own risk
