This is part of a series of changes to minimize the number of spans committed to EditText, as a mitigation for platform issues on Samsung devices. See this [GitHub thread]( https://github.com/facebook/react-native/issues/35936#issuecomment-1411437789) for greater context on the platform behavior.
This change lets us set `letterSpacing` on the EditText instead of using our custom span.

This change makes us apply strikethrough and underline as paint flags to the underlying EditText, instead of just the spans. We then opt ReactUnderlineSpan and ReactStrikethroughSpan into being strippable.
This does actually create visual behavior changes, where child text will inherit any underline or strikethrough of the root EditText (including if the child specifies `textDecorationLine: "none"`. The new behavior is consistent with both iOS and web though, so it seems like more of a bugfix than a regression.

We cache the backing EditText span on text change to later measure. To measure outside of a TextInput we need to restore any spans we removed. Spans may overlap, so base attributes should be behind everything else.
The logic here for dealing with precedence is incorrect, and we should instead accomplish this by twiddling with the `SPAN_PRIORITY` bits.

Because we've stripped the sizing spans, Spannable measurement has incorrect font size, and the TextInput size will change (collapsing) after the first edit. This effectively breaks any uncontrolled TextInput which does not have explicit dimensions set.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/35967
In https://github.com/facebook/react-native/issues/35936 we observed that the presence of AbsoluteSizeSpan may lead to hangs when using the Grammarly keyboard on Samsung.
This mitigation makes it so that we do not emit this span in any case where it is sufficient to rely on already set EditText textSize. In simple cases, tested on two devices, it causes typing into the TextInput to no longer hang.
This does not fully resolve the issue for TextInputs which meaningfully use layout-effecting spans (or at least font size), such as non-uniform text size within the input. We instead just try to reduce to minimum AbsoluteSizeSpan possible.
Testing the first commit was able to resolve hangs in some simpler inputs tested, by me and cortinico.

In the old renderer, we explicitly reset all animated props, and wait for the subsequent React commit to set the props to the right state, but if `initialProps` are used, the React reconciliation may not be able to identify the prop-update is required and will leave out the value. This behaviour is different in the new renderer, where we do not explicitly `restoreDefaultValues` on detaching the animated node, and instead rely on the latest state being correct(?).

Summary:
When the webview is updated by play store, all apps that has loaded webview gets killed. For background see https://issuetracker.google.com/issues/228611949?pli=1
We have a long-running app and don't want this to happen and while we are not using webview anywhere, we are using websockets that loads it for reading cookies, however we are not using cookies to authenticate the websocket and thus want to disable the webview to avoid loading it unnecessarily and then getting killed unnecessarily.
The webview has support for beeing disabled https://developer.android.com/reference/android/webkit/WebView#disableWebView() however as-is this crashes React Native. It seems to me like this case is very similar to not having web view installed and should be handled in the same way.

Summary:
While I was working on rewriting `react-native-slider` to Fabric I found a weird bug that prevented the slider to be set as disabled (to be exact: call the method `slider.setEnabled(false)`. As it turned out the `accessibilityState` (with value: `accessibilityState={{disabled: true}}` prop occurred after the `enabled={false}` prop that I was passing to the slider, which lead to both of this props overwrite each other.
Handling of `accessibilityState` props inside view leads to always overwriting the enabled prop to true (even if we explicitly set it to `{disabled: false}`.
Workaround for this was to reorder the props, so that the `accesibilityState` occur before `disabled`, but I think it's better to not set `view.setEnabled(true)` if we are passing a disabled property.

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).

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.

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.
