Paige Sun 743d0706e2 1/3 Add validation reporting APIs for unexpected uses of Paper when Fabric is enabled, in Bridge mode
Summary:
Changelog: [Internal][iOS] Add validation reporting APIs for unexpected uses of Paper when Fabric is enabled

## RCTNotAllowedInBridgeless
Previously, we only had violation reporting APIs for when **Bridge APIs** are used in **Bridgeless mode**, which was only enabled in Bridgeless mode.

## RCTNotAllowedInFabric
This diff adds violation reporting APIs to use when **pre-Fabric Bridge APIs** are used in **Bridge or Bridgeless mode**. This allows us to add RCTAssert/RCTError/RCTLog to more APIs in Bridge mode. The main purpose is to distinguish between Bridge APIs that still work in Fabric, versus Bridge APIs that are no longer used in Fabric, so that the latter can be removed.

Diego Pasquali 7b05b091fd Integrated iOS-only accessibilityLanguage prop (#33090)
Summary:
This PR fixes https://github.com/facebook/react-native/issues/30891

This PR is going to add an `accessibilityLanguage` prop to all the available components. This props is currently working only on iOS and should follow the [guidelines of the relative configuration](https://developer.apple.com/documentation/objectivec/nsobject/1615192-accessibilitylanguage).

I'm in no way an expert on native programming (especially Objective-C) so I'm open to changes / improvements 🙂

## Changelog

<!-- Help reviewers and the release process by writing your own changelog entry. For an example, see:
https://github.com/facebook/react-native/wiki/Changelog
-->

[iOS] [Added] - Integrated the `accessibilityLanguage` prop to all the available components. The prop is available for any platform but it will work only on iOS.

Pull Request resolved: https://github.com/facebook/react-native/pull/33090

Test Plan:
This has been tested using both the Simulator, checking for the `Language` attribute, and using a physical device with the Voice Over enabled.

Justin Huntington bc1e602e0c Add ScrollView.automaticallyAdjustsScrollIndicatorInsets prop (on iOS) (#29809)
Summary:
iOS 13 added a new property to `UIScrollView`: `automaticallyAdjustsScrollIndicatorInsets`, which is `YES` by default.  The property changes the meaning of the `scrollIndicatorInsets` property.  When `YES`, any such insets are **in addition to** whatever insets would be applied by the device's safe area.  When `NO`, the iOS <13 behavior is restored, which is for such insets to not account for safe area.

In other words, this effects ScrollViews that underlay the device's safe area (i.e. under the notch).  When `YES`, the OS "automatically" insets the scroll indicators, when `NO` it does not.

There are two problems with the default `YES` setting:

1. It means applying `scrollIndicatorInsets` to a `ScrollView` has a different effect on iOS 13 versus iOS 12.
2. It limits developers' control over `scrollIndicatorInsets`.  Since negative insets are not supported, if the insets the OS chooses are too large for your app, you cannot fix it.

Further explanation & sample code is available in issue https://github.com/facebook/react-native/issues/28140 .

This change sets the default for this property to `NO`, making the behavior consistent across iOS versions, and allowing developers full control.

Shuhao Zhang f3b8d4976f Bug fix: <TextInput> content is reset when emoji is entered at the max length
Summary:
When maxLength is defined in <TextInput>, if the last character at max length is an emoji, the content of the input is cleared:

{F620865178} {F620865237}

Related Github issues:

https://github.com/facebook/react-native/issues/10929
https://github.com/facebook/react-native/issues/10964

## Root cause:

When NSString was created, unicode characters were 16-bit long, so Objective-C considers every unicode character as 16-bit. However, unicode was later extended to more than 16bit, for example, emojis, which causes NSString substring method cuts off at the wrong position.

Example:

```
NSString *s = @"abc{emoji:1f601}";
NSInteger len = s.length; //length is 5 (as {emoji:1f601} occupies two 16-bit characters)
NSString *s3 = [s substringToIndex: 3]; //s3 is "abc"
NSString *s4 = [s substringToIndex: 4]; //s4 is null!
```

If string s, "abc{emoji:1f601}", is entered in <TextInput>, which has max length 4, it will truncate the string to the first 4 characters, "cutting" the emoji in half which causes encoding error and returns null. The text input is cleared.

## Solution:

If the character at max length is longer than 16-bit, truncate the character BEFORE it instead. In the previous example, truncate till index 3 instead of 4. The end result will be "abc" and the emoji is dropped.

## Changelog:

[iOS] [Fixed] - <TextInput> content is reset when emoji is entered at the max length

Samuel Susla a18a2de4b4 Fix crash in ~Pointer by not retaining LayoutManager beyond the runtime
Summary:
Changelog: [internal]

This is a life cycle issue where LayoutManager outlives the runtime. To fix this, we need to destroy `_accessibilityProvider` before the runtime. The way to do it is to destroy it inside `prepareForReuse` which is guaranteed to be called before runtime is destroyed.

Summary:
Changelog: [internal]

There is a possibility of race between updating scrollview's state and virtualised list asking for layout of individual cells.
To make sure the race doesn't happen, state must be updated before dispatching onScroll event.
