Krystof Woldrich c4082c9ce2 surface uncaught promise rejections with ExceptionsManager.handleException instead of swallowing them (#51594)
Summary:
This PR fixes logging of rejections, which stopped working with the transition from using `LogBox` for warnings to directing users to use React Native Debugger, where warnings can be viewed in the `Console` tab.

Rejected promises before this PR used `LogBox.addLog` with the `level: warn` directly without `console.warn`, which notified users to open debugger to view a warning (after rejected promise) without actually printing any warnings to the console.

This PR uses `ExceptionsManager.handleException(error, false /* isFatal */);` for promise rejections that correctly raising an error to the console if needed.

### Rejected Promise in Chrome
Displaying the error as long as it's uncaught in the form:
`Uncaught (in promise) Error`
and if there's a message in that error:
`Uncaught (in promise) Error: ${message}`
once the error is handled, this error disappears:
{F1978806409}
This is done with `Runtime.exceptionThrown`, and  `Runtime.exceptionRevoked`:
{F1979815326}

## Changelog:
[General][Breaking] unhandled promises are now handled by ExceptionsManager.handleException, instead of being swallowed as Logbox Warnings.
----
This is a breaking change because we changed the wording for these errors and because some systems (like Sentry) might start monitoring a new set of errors when this code is adopted.

Pull Request resolved: https://github.com/facebook/react-native/pull/51594

Test Plan:
Use `Promise.reject` and observe that the rejection is now shown symbolicated in LogBox and also printed in React Native Debugger Console.

```
<Button
  title="Uncaught Promise Rejection"
  onPress={() => {
    const err = new Error('test error');
    err.cause = new Error('cause');
    const promise = Promise.resolve().then(() => {
      throw err;
      // also test with throwing a string / object:
      // throw 'aa';
      // throw {test: 'object'};
      // return Promise.reject();
    });

    setTimeout(() => {
      promise.catch(e => {
        console.log('promise error caught', e);
      });
    }, 4000);
  }}
/>
```

### Before
There's no indication whatsoever there's an uncaught promise.

### After
An error is logged:
Error-
{F1979749366}
Text-
{F1979749350}
Object-
{F1979749351}
Promise.reject() or undefined-

Rubén Norte 2d4c43c267 Fix incorrect locking in ShadowTree experiment (#52662)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52662

Changelog: [internal]

In the original change I made in D78418504 / https://github.com/facebook/react-native/pull/52645 I made a mistake and used a lock that would try to re-lock on itself without it being recursive (which would cause a deadlock). I didn't see that because when testing I didn't hit the case where we'd exhaust the options.

This propagates a flag to `tryCommit` to indicate we've already locked on the `commitMutex_` so we don't need to lock again in that case, fixing the issue.

Pieter De Baets a9ece0c302 Use native helpers to accelerate transform processing (#52603)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52603

Processing transforms is expensive in Java, as it requires bridging the entire ReadableNativeArray/Map. Instead, we can use the existing parser logic `resolveTransform` logic to perform this operation in C++.

Ideally, we actually re-use the existing parsed transform from Props, that could be something we revisit after Props 2.0.

As a follow-up, we should consider also moving the matrix decomposition logic from MatrixMathHelper here, and make that the only information we send back to Java.

We compare the current transform (represented as a ReadableArray) with the incoming one to know whether to invalidate. This can be expensive as it requires to materialize the entire transform data structure over JNI. Instead, we can delegate this comparison to native code, which can compare the underlying folly::dynamic directly.

Pull Request resolved: https://github.com/facebook/react-native/pull/52613

Changelog: [internal]

This adds first-class support for the `detail` field in `performance.mark` and `performance.measure`.

Now that we have access the JS entry in native, we can access the `detail` field to propagate it to DevTools (and use it to extract track names for Perfetto).

In order to avoid the performance overhead of always having to extract the `detail` field from the entry, this is done lazily only if we're actively profiling with DevTools or Perfetto.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52586

Changelog: [internal]

This fixes a "bug" (or spec-compliance issue) in the `performance.measure` method where `end` and `duration` couldn't be used together (only `start` and `duration`, and `start` and `end` could be used).

This also refactors the API to be "JS-first", preparing the native module methods to support passing instances of entries to fix other issues.

Verified performance impact: `mark` is slightly regressed (~7% slower) due to an additional JSI call to get the default start time and `measure` is significantly optimized (25/30% faster) due to simplified parameter handling in JSI calls.

Riccardo Cipolleschi 21b93d8d7d Fix RefreshControl recycling (#52584)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52584

The method `_initializeUIRefreshControl` creates a new instance of `UIRefreshControl` which has the default values for things like tint color.
However the props that we are keeping in the component are the `_props` before recycling. The actual state of the newly created UIRefreshControl is out of sync w.r.t the props the component thinks to have.

By introducing a `_recycled` state variable, we can force the first `updateProp` call to apply all the props to the newly created component.

## Changelog:
[iOS][Fixed] - Make sure that the recycled refresh control have the right props setup.

Mateo Guzmán 42b8921d91 Kotlin: Set up ktfmt in OSS (#52064)
Summary:
This PR adds the basic `ktfmt` setup in OSS to lint Kotlin files before they're imported into the Meta codebase, making collaboration with external contributors smoother for Android related PRs.

I tried to put together certain rules that mimic the current code style and it seems to work well as I get no errors for properly formatted files but this still might need some input to have the correct configuration.

Added two scripts to the main package.json:
- To check the files format you can run: `yarn lint-kotlin-check`
- To apply formatting fixes, run: `yarn lint-kotlin`

## Changelog:

Abhijeet Jha f004cd39bc Text: Fix isSelectable prop macro conversion (#52599)
Summary:
for IOS and React native windows we can observe that the macro conversion is incorrect in ParagraphProps particularly for selectable prop.

current conversion
```
case ([]() constexpr -> RawPropsPropNameHash {   return facebook::react::fnv1a("isSelectable");  }()): fromRawValue(context, value, isSelectable, defaults.isSelectable); return;
```
issue is that isSelectable is not the raw prop therefore JS to native flow for the prop is not correct .
(Note : this works for Android as ReactProp(name = "selectable"):  https://github.com/facebook/react-native/blob/bbc1e121c71d14803d29a931f642bf8ea6ee2023/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/views/text/ReactTextAnchorViewManager.kt#L97-L100 )

fix
```
RAW_SET_PROP_SWITCH_CASE(isSelectable, selectable)
```

Current implementation selectable prop is not working for IOS and React native windows as the macro conversion is incorrect in ParagraphProps particularly for selectable prop.

## Changelog:
Updated ParagraphProps macro conversion for isSelectable , keeping it backward compatible.

           This text is not selectable. You cannot copy it.
        </Text>
      </View>
    );
  }
}

Nick Gerleman 7f224941bb Disable Android Workarounds for Attachment Metrics (#52446)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52446

The logic for retrieving metrics from a placeholder character is kind of insane, and has been around since inline views were added built into TextView in Paper.

One of the workarounds, for old versions of Android on Samsung phones (no more info to bound the versions) causes incorrect behavior, at least in the case where we have RTL text in LTR layout.

Another, explicitly mentions `singleLine` with RTL para, a deprecated TextView prop, that doesn't apply to us here (and also could never apply to BoringLayout, since RTL chars are not boring).

We don't have these workarounds anywhere else (though we have some other workarounds for bidi crash in old Android), including other frameworks I could find.

Let's bias to cleaning this old code up.
