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`.

[General] [Fixed] - Fix FlatList not calling render items for nullish values when numColumns > 1
Pull Request resolved: https://github.com/facebook/react-native/pull/34205
Test Plan:
- I added a failing test corresponding to the issue, and the test now succeeds.
- I used the same code as in the test on a newly initialized app on RN 0.69 and made sure renderItem was called for every items as expected.

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:
# 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. See https://reactjs.org/docs/events.html#supported-events

[General][Added] - Add types for onFocusCapture/onBlurCapture

Summary:
We are already returning the `remove` function, and the `removeEventListener` method has been removed in this PR: https://github.com/facebook/react-native/issues/33580. So I believe this comment is now outdated and no longer relevant.

Summary:
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.

Summary:
Currently, with the Alert API on iOS, the only way to bold one of the buttons is by setting the style to "cancel". This has the side-effect of moving it to the left. The underlying UIKit API has a way of setting a "preferred" button, which does not have this negative side-effect, so this PR wires this up.
See preferredAction on UIAlertController https://developer.apple.com/documentation/uikit/uialertcontroller/
Docs PR: https://github.com/facebook/react-native-website/pull/2839
## Changelog
[iOS] [Added] - Support setting an Alert button as "preferred", to emphasize it without needing to set it as a "cancel" button.
Pull Request resolved: https://github.com/facebook/react-native/pull/32538
Test Plan:
I ran the RNTesterPods app and added an example. It has a button styled with "preferred" and another with "cancel", to demonstrate that the "preferred" button takes emphasis over the "cancel" button.

Summary:
A layout-impacting style change will trigger a layout effect hook within `TextInput`. This hook fires a ViewManager command to set the text input based on the known JS value: https://github.com/facebook/react-native/blob/d82cd3cbce1597512bb2868fde49b5b3850892a0/Libraries/Components/TextInput/TextInput.js#L1009
The JS value is determined using `value` if set, falling back to `defaultValue`. If a component uses `TextInput` as an uncontrolled component, and does not set this value, the command wipes text input back to the default value. This does not happen on re-render of the JS side, despite setting text prop, since the underlying native property never changes/triggers a rerender.
This change alters the logic to prefer `lastNativeText` instead of `defaultValue` when available, to retain the updated `TextInput` content on relayout.

Summary:
Ahead of enabling the `exact_empty_objects` option, suppress errors so that actually enabling the option is easier. We can do this without enabling the option by codemoding `{}` to `{...null}` in files that have errors.
Process:
1) Get list of files with errors when enabling the option
2) Codemod `{}` to `{...null}` in those files
3) Suppress resulting errors
4) Land diff with `drop-conflicts` flag
5) Announce and enable option (with many fewer files to edit)
6) Codemod all `{...null}` to `{}`
drop-conflicts
We are working on making the empty object literal `{}` have the type `{}` - i.e. exact empty object - rather than being unsealed.

Summary:
```js
async () => {
let blobs = [];
for (let i = 0; i < 4; i++) {
const res = await fetch();
blobs = [...blobs, await res.blob()]
}
const blob = new Blob(blobs); // <<<<<<<<<<<<<<< a
return await new Promise((resolve, reject) => {
const fileReader = new FileReader();
fileReader.onload = async () => {
await RNFS.writeFile(destPath, (fileReader.result as string).split(',')[1], 'base64');
resolve(destPath);
};
fileReader.onabort = () => {
reject('');
};
fileReader.onerror = (event) => {
reject('');
};
fileReader.readAsDataURL(blob); // <<<<<<<<<<<<<<< b
});
}
```
Sometime `fileReader.readAsDataURL` is unable to get blob from the dictionary after `new Blob(blobs)` and then reject with `Unable to resolve data for blob: blobId` in iOS or `The specified blob is invalid` in android. Because line `a` and `b` can be run in different thread. `new Blob([])` is in progress and `fileReader.readAsDataURL` accesses the blob dictionary ahead of the blob creation.
The expected behaviour is it should finish new Blob([]) first and then readAsDataURL(blob)
To fix that, there should be a lock inside the method `createFromParts`. For iOS, It needs to be a recursive_mutex to allow same thread to acquire lock

Summary:
`InputAccessoryView` works fine on iOS, but crashes on Android - you can see that by using an Android device on the [Expo Snack from the official doc](https://reactnative.dev/docs/inputaccessoryview).
It forces the developer not to render the component on Android, which is usually good, but other components have implemented other, safer ways to deal with incompatibility issues.
I am of course open to discussion about this change, as well as other implementation ideas.
