[General][Changed] - Copied and refactored the current devtools highlighting code from Inspector into its own module and add to the top level `AppContainer`. The effect is that the highlight stills shows without Inspector opened.
This diff copies the current devtools highlighting logic from Inspector into a module and add to the top level `AppContainer`. The effect is without Inspector opened, the highlight will still show.
## Context
This is the first diff for "Component Tab Automatically Highlight Elements". The idea is to replicate the behavior on Web to RN.
## Behavior
on Web:
- highlight shows whenever an element in the component list is hovered
- Selecting an element doesn't keeps the highlight showing.
on RN (before this diff):
- when RN inspector opens: selecting an element keeps the highlight showing
- when RN inspector closes: stop showing highlihgintg.
on RN(this diff)
- selecting an element keeps the highlight showing
## TODO
- See if highlighting event can be sent on hover, instead of when an element is selected.

Summary:
This adds an option to the Error Reporting pipeline of React Native to attach custom extra data to Exceptions passed to the native ExceptionsManager. This allows for error logging abstractions such as Meta's FBLogger to attach extra fields to the reported error. This can help with more detailed error reports without having to stringify all data in the error message.
Note: The field (which is technically on ExtendedError) is keyed using a Symbol. This is to make sure that any use of this ability is extremely deliberate, as (accidentally) adding tons of data (or unserializable data) can cause issues we send down the data to the native ExceptionsManager implementation. Data sent using this method should be strictly controlled, hence opting in is a concious effort using the symbol in ExceptionsManager

[General][Fixed] - Run ExceptionsManager unit tests in both __DEV__ and prod mode
This suite of unittests use a `__DEV__` check in various places to check that the correct data is sent to either LogBox (in __DEV__) or the Native ExceptionsManager (in PROD). However, we're not actually running both modes, so half of the assert branches in these tests aren't ever utilized.
This diff uses the same approach as ReactNativeVersionCheck-test.js to execute this test suite twice: Once in DEV and once in PROD mode.

Summary:
Currently both iOS and Android send over the list of transforms as an array. But there is an if statement that causes other platforms to get a matrix. This prevents other platforms from being able to use the fabric ViewProps class and the conversion functions as they exist in core, as those expect the transforms to be an array.
Stop special casing iOS and android. - Which will allow for example Windows to be able to share more fabric code.

Sometime over the past few months (and with changes such as migrating to the `hermes-eslint` parser), a bunch of lint warnings crept into the codebase.
This does a pass to clean them all up, ignore generated files, and refactor some code to be... better.

Cleans up a few minor Flow suppression comments in `FlatList`. This reveals a new Flow error that is the result of `FlatList`'s props object being inexact whereas `VirtualizedList`'s props object is exact. For now, I introduce another -- but more specific -- Flow suppression for that type error.

Summary:
RN for Android fires `keyboardDidShow` and `keyboardDidHide` by observing changes to viewable window size. This isn't always reliable, such as when an activity has `awindowSoftInputMode` set to not have the system adjust the viewport when a keyboard is opened.
Android 11 added the direct ability to measure and check visibility of the soft keyboard via `WindowInsets`, which fixes these issues. This is exposed downlevel to API 23 via WindowInsetsComapt` with the same limitations as previously, but using it simplifies our calculations a lot.

Summary:
Previously published by [grgr-dkrk][2] as [https://github.com/facebook/react-native/issues/31296][3], fixes the following issues:
1) ImportantForAccessibility="no" does not work on Text, Button
2) ImportantForAccessibility="no-hide-descendants" does not work on Text, Button, or ImageBackground.
Note: On ImageBackground, focus is prevented on the imageBackground node itself, but focus is not prevented on its descendants.
Note: [Button component expected behavior for prop importantForAccessibility][4]
>Some components like Button seem like atomic units, but they end up rendering a hierarchy of components for example a wrapper View with a Text inside them. Allowing those descendants to become focusable, breaks the model of these being a single component to consider and forcing no-hide-descendants makes sense here.
>The other option is always to render any descendants of these elements with importantForAccessibility="no", so they can never be focusable on their own. This would have the same result, **BUT may potentially cause issues when the descendant content is supposed to automatically get moved up to the focusable ancestor to act as a label** (which is what Talkback does with unfocusable text elements by default).
Note: [importantForAccessibility="no" does not allow screenreader focus on nested Text Components with accessibilityRole="link" or inline Images][5]

Summary:
This diff is part of an overall stack, meant to fix incorrect usage of `setState()` in `VirtualizedList`, which triggers new invariant checks added in `VirtualizedList_EXPERIMENTAL`. See the stack summary below for more information on the broader change.
## Diff Summary
This adds a `StateSafePureComponent`, which will override `setState`, along with `this.props` and `this.state`, in order to add runtime enforcement that `this.props` and `this.state` are not accessed during a state update where we should be relying on parameter instead. This should be landed after the fixes for unsafe `this.props`/`this.state` usage.
## Stack Summary
`VirtualizedList`'s component state is a set of cells to render. This state is set via the `setState()` class component API. The main "tick" function `VirtualizedList._updateCellsToRender()` calculates this new state using a combination of the current component state, and instance-local state like maps, measurement caches, etc.

> React may batch multiple setState() calls into a single update for performance. Because this.props and this.state may be updated asynchronously, you should not rely on their values for calculating the next state. For example, this code may fail to update the counter:

counter: this.state.counter + this.props.increment,
});
```
> To fix it, use a second form of setState() that accepts a function rather than an object. That function will receive the previous state as the first argument, and the props at the time the update is applied as the second argument:
```
// Correct
this.setState((state, props) => ({
counter: state.counter + props.increment

Summary:
Fixes https://github.com/facebook/react-native/issues/34034.
The FlatList doesn't call renderItem on nullish values when numColumns > 1, but it does when numColumns is not set (or equals 1).
I think the behavior should be consistent, so I updated the code so renderItems is called for every items.
I believe the condition `item != null` was here to make sure renderItem isn't called for index outside of data range, so I replaced it with `itemIndex < data.length`.

Summary:
This diff is part of an overall stack, meant to fix incorrect usage of `setState()` in `VirtualizedList`, which triggers new invariant checks added in `VirtualizedList_EXPERIMENTAL`. See the stack summary below for more information on the broader change.
## Diff Summary
This moves public VirtualizedList types to a new file, shared between both `VirtualizedList`, and `VirtualizedList_EXPERIMENTAL`. This allows us to make public interface changes in a single place.
## Stack Summary
`VirtualizedList`'s component state is a set of cells to render. This state is set via the `setState()` class component API. The main "tick" function `VirtualizedList._updateCellsToRender()` calculates this new state using a combination of the current component state, and instance-local state like maps, measurement caches, etc.

counter: this.state.counter + this.props.increment,

this.setState((state, props) => ({

Summary:
VirtualizedList state is represented in terms of [first, last] ranges, where it is possible to express a zero-cell range by having [n, n-1]. This includes some awkward examples, like [0, -1] being valid.
CellRenderMask assumes `addCells` is called with at least one cell, with VirtualizedList previously guarding against adding the no cell case. This guard is present for adding main cell regions, but not for `_initialRenderRegion()`, which can be overridden to have a zero length as well.
This moves the `CellRenderMask` to be permissive of zero-length cell regions, and removes the caller guard.

Summary:
If FlatList is passed non-array data it will return `undefined` as the result of `getItemCount()` to VirtualizedList. This change makes it return `0` instead, to signify there are no valid items to attempt to accces.
There are a set of invariants on properties passed to FlatList, to curb incorrect types at runtime, but there is existing code which runs into the condition.

Summary:
# This Change
https://github.com/react-native-community/discussions-and-proposals/pull/335 discussed a set of problems with VirtualizedList and focus. These were seen as severe externally for a11y on desktop. The issues center on users of keyboard and accessibility tools, where users expect to be able to move focus in an uninterrupted loop.
The design and implementation evolved to be a bit more general, and without any API-surface behavior changes. It was implemented and rolled out externally as a series of changes. The remaining changes that were not upstreamed into RN are rolled into https://github.com/facebook/react-native/pull/32646
This diff brings this change into the repo, as a separate copy of VirtualizedList, to measure its impact to guardrail metrics, without yet making it the default implementation. The intention is for this to be temporary, until there is confidence the implementation is correct.
## List Implementation (more on GitHub)
This change makes it possible to synchronously move native focus to arbitrary items in a VirtualizedList. This is implemented by switching component state to a sparse bitset. This was previously implemented and upstreamed as `CellRenderMask`.
A usage of this is added, to keep the last focused item rendered. This allows the focus loop to remain unbroken, when scrolling away, or tab loops which leave/re-enter the list.
VirtualizedList tracks the last focused cell through the capture phase of `onFocus`. It will keep the cell, and a viewport above and below the last focused cell rendered, to allow movement to it without blanking (without using too much memory).
## Experimentation Implementation
A mechanism is added to gate the change via VirtualizedListInjection, mirroring the approach taken for Switch with D27381306 (https://github.com/facebook/react-native/commit/683b825b327e7fa71e87e3d613cb9acd37c24288).
It allows VirtualizedList to delegate to a global override. It has a slight penalty to needing to import both modules, but means code which imports VirtualizedList directly is affected the changes.

Summary:
This change is in preparation of adding a separate `VirtualizedList_EXPERIMENTAL` component.
Both the original, and experimental lists use `VirtualizedListContext`, which itself references back to the VirtualizedList class type. VirtualizedList private methods are currently included in the type system, and are called in other VirtualizedList code (see https://github.com/facebook/react-native/commit/b2f871a6fa9c92dd0712055384b9eca6d828e37d). This prevents Flow from seeing the two classes are compatible if "private" methods change.
My first attempt was to parameterize the context, to allow both `VirtualizedList`, and `VirtualizedList_EXPERIMENTAL` to use the same code without sacrificing type safety or adding further duplication. This added more complexity than it is worth, so I am instead loosening the type on VirtualizedListContext to pass around a more generic handle.

Summary:
The `NSMutableAttributedString` was initialized with the same backing store as the cached attributed string on the shadow queue (background thread), but then passed to the main thread and ultimately the JS thread.
This explicitly copies the mutable attributed string into an immutable one on the shadow thread before passed off to other threads, which hopefully will address the `convertIdToFollyDynamic` crash that always includes `RCTBaseTextInputShadowView` touching an attributed string on the shadow queue in the trace.

Summary:
Add capture-phase focus events to the type system, for use in the refactored VirtualizedList https://github.com/facebook/react-native/pull/32646/files
Tracking the last focused child is done via focus events. Focus events are bubbling (vs direct events like onLayout), and are given both a "capture" phase, and "bubbling phase", like DOM events on the web. https://stackoverflow.com/questions/4616694/what-is-event-bubbling-and-capturing
The VirtualizedList change wants to know if a child will receive focus. This is not possible to reliably capture in the bubbling phase, since a child may stop propagation.
See https://github.com/react-native-community/discussions-and-proposals/pull/335#discussion_r584851337 for some discussion with Scott Kyle about this issue back in the day
This is done by convention in React by adding a "capture" variant of the `onXXX` method. For all platforms I've seen with focus events, these map the `topFocus` native event to `onFocus` for bubbling phase, and `onFocusCapture` for capture phase.

A crash encountered in react-native-macOS is very similar to one fixed by https://github.com/microsoft/react-native-macos/pull/489#discussion_r451789471 (see discussion), and it's possible this `replacement` string also suffers from sharing the same backing store as the attributed string (maybe only when the range encompasses the entire string?) and therefore should be copied as well.
