Summary:
Note: PR to react-native-macos here https://github.com/microsoft/react-native-macos/pull/733
Internally in Microsoft code, we ran into a deadlock where the main queue and the UIManager queue were both trying to access `[RCTI18nUtil sharedInstance]`, and were blocked on each other. This is similar to an earlier issue with RCTScreenScale decsribed [here](https://github.com/facebook/react-native/issues/18096).
To summarize:
1- RCTShadowView (on the UIManager queue) and RCTView (on the main queue) both try to access `[RCTI18nUtil sharedInstance]`
2- The UIManager thread gets there first, and lazily initializes the sharedInstance. Meanwhile, the main thread is waiting on a lock possessed by the UIManager thread
3- As part of the initialization, we set an NSUserDefault, which seems to require the (blocked) main thread.
4- Deadlock.
For whatever reason, this only happens on debug. I did not figure out why, but I do know based on [this comment](https://github.com/facebook/react-native/issues/18096#issuecomment-368718081), that the UIManagerQueue should never block the main queue.
The fix is to not use NSUserDefaults, and simpy use atomic properties instead. We get the thread safety for free, and it also simplifies the code somewhat without changing the public API. The downside is values aren't persisted anymore, but I do not think that was necessary / intended.

[iOS] [Fixed] - Fix deadlock on RCTi18nUtil
Pull Request resolved: https://github.com/facebook/react-native/pull/31032
Test Plan:
Ran the RTLExample in RNTester, and ensured switching to RTL still worked, and that setting forceRTL would still work after reloading the bundle.

Summary:
changelog: [internal]
If nodesManager has the information if animated node is managed by Fabric, we can't decide if the operation queue should be flushed before it is flushed. Therefore, keep the information about animated nodes inside a set instead of nodesManager.
For simplicity, I will refer to class `RCTNativeAnimatedTurboModule` as *NativeAnimated* and to `RCTNativeAnimatedNodesManager` as *NodesManager*
Notice that each call to *NativeAnimated* is queued up in `_operations` or `_preOperations`. When the queues are flushed, only then methods are called on `RCTNativeAnimatedNodesManager`.
There are two mechanisms that flush operations.
One is triggered by `RCTMountingManager` before mounting operations are applied and after they are applied. This works fine but is important to paint the picture.
The second mechanism is inside `[RCTNativeAnimatedTurboModule startAnimatingNode]`. It flushes the queues for Fabric nodes only (not sure why Fabric nodes only, I couldn't find any explanation in old diffs). It checks with *NativeAnimated* if a node is managed by Fabric. Keep in mind, *NodesManager* only knows about the nodes when the queues have been flushed.
Exampe:
JavaScript calls methods on *NativeAnimated*.
For example:
1. `createNode`
2. `connectAnimatedNodeToView`
3. `startAnimatingNode`. (here, the queues should be flushed, since we are in Fabric)
All of these operations are queued up and for as long as `RCTMountingManager` executes mounting, all proceeds as expected.
But if those operations happen after mounting phase, `startAnimatingNode` will not flush the operations queues, because it can't tell if nodeTag is managed by fabric or it isn't. This is because *NodesManager* hasn't been notified about any new nodes.

Make sure the order of call is preserved for `NativeAnimatedModule`. The order of calls to NativeAnimatedModule needs to be preserved because its internals depend on it. For example, if you `getValue` is called before `createAnimatedNode`, it causes a crash.
To resolve it, we need to enqueue `getValue` onto operationQueue.

Summary:
This small PR updates the Flow types used in Dimensions. The following changes has been made:
* generic types has been replaced with types from `NativeDeviceInfo` (which already were used in event subscription update)
* ~simplification of `DisplayMetricsAndroid` by spreading via intersection with `DisplayMetrics` type and removing shared properties~
> I have tried both notations, but according to the lint, it looks like a Native Modules typing limitation which requires redundancy / code duplication in cases like this.

Summary:
It seems that, possibly due to optimizations and refactoring elsewhere in the event system, some TouchEvents are being over-disposed.
This doesn't really pose a problem besides performance; and could even indicate that an Event was in a pool but never properly initialized. In these
cases it seems perfectly reasonable to silently continue, and to log a soft exception. This WILL still crash in debug mode, so we can gather more information
if we find a good repro; otherwise we will continue to get production data from this soft exception if it's an issue and we can investigate further.
