Files that are inside `xcshareddata` are meant to be "shared", and that means committed to git. These files are for example `ios/RnDiffApp.xcodeproj/xcshareddata/xcschemes/RnDiffApp.xcscheme`, and if ignored that means they are removed from the repo or are missing when cloning. These should be present. They are the shared schemes so Xcode knows what and how to build, on everyone's machine.

Summary:
We currently have a method in ReactContextBaseJavaModule that logs a warning if the native module is trying to access a ReactContext without an active Catalyst instance (because if you try to access it directly, it throws).
For bridgeless mode, we never have a CatalystInstance, but it's safe to call certain methods on the context that would normally require one. For this case, let's just return the context when the context is in bridgeless mode.

Summary:
We currently use `BatchedBridge.registerCallableModule` to call JS from platform code in a bunch of places (e.g. `RCTDeviceEventEmitter.emit()`), including some pretty essential ones - for example, Networking relies on `RCTDeviceEventEmitter` to emit events to JS for network requests and errors. In order to make the migration to bridgeless mode as easy as possible, it'd be best if we didn't have to update all the callsites in JS and platform code, at least for core JS modules like `RCTDeviceEventEmitter`. So we'd like to implement this callable module pattern for bridgeless mode as well.
In this diff, I'm installing a global variable, `RN$registerCallableModule`, which will store the JS module name and factory function in C++. This can then be called from platform code (Java/Obj-C) to invoke a JS function on a module using the existing APIs (`context.getJSModule()` on Android, `enqueueJSCall()` or similar on iOS).

Summary:
Some babel plugins add additional methods to `Function.prototype` (see https://github.com/MatAtBread/fast-async):
```js
Function.prototype.$asyncbind = function $asyncbind(self, catcher) {
...
```
Although undocumented, React Native allows functions to be passed to `StyleSheet.create()` for dynamic styling:
```js
const styles = StyleSheet.create({
animalItem: height => ({ height })
});
```
If there are additional custom methods on `Function.prototype`, React Native's `StyleSheetValidation.validateStyle` will loop through these properties and raise an error because those properties are not valid style keys, because it loops through _all_ properties, including inherited ones.

This PR modifies `StyleSheetValidation.validateStyle` to only loop through the style's own properties, instead of including inherited ones.

Summary:
In https://github.com/facebook/react-native/issues/25427, radex added initial support for running React Native projects on macOS via Catalyst. However, `RCTWebSocket` was disabled for that target because of some compilation issues. This meant that running projects via a connection to the packager wasn't possible: no live reload, and projects must be run in "Release" mode. It also meant making manual changes to Xcode projects deploying to macOS and scattering a number of conditional checks throughout the codebase.
In this change, I've implemented support for `RCTWebSocket` on the macOS target and re-enabled the affected features. Live reload and the inspector now work for macOS targets. Manual modifications of Xcode build settings are no longer necessary for react-native projects running on macOS.

### Limitations
There's no binding which displays the developer menu (since there's no shake event on macOS). We'll probably want to add one, perhaps to the menu bar.
I've chosen not to commit the modifications to RNTester which enable macOS support, since that would imply more "official" support for this target than I suspect you all would like to convey. I'm happy to add those chunks if it would be helpful.
## Changelog
[iOS] [Added] - Added web socket support for macOS (Catalyst), enabling debug builds and live reload
Pull Request resolved: https://github.com/facebook/react-native/pull/27469
Test Plan:
* Open RNTester/RNTester.xcodeproj with Xcode 11.2.1, run it like a normal iOS app -- make sure it compiles and runs correctly (no regression)
* Select "My Mac" as device target, and run. You may need to configure a valid development team to make signing work.
* RNTester should run fine with no additional configuration. Modify a file in RNTester, note that live reload is now working.
* Test the developer inspector. To display the developer menu, you'll need to manually show it; here's an example diff which does that:

Summary:
The `RCTImageURLLoaderWithAttribution` protocol historically only returns a cancellation block to cancel the url request. But for more complex instrumentation, we may need to associate a requestId for the specific URL request. To do this, the protocol now returns an object that has both the unique ID and the cancellation block, so that instrumentation logic can refer to the ID in the future.
Note that the `RCTImageURLLoader` protocol is unchanged, because the request ID is only relevant for instrumentation purpose.

Summary:
Motivation: in Marketplace, there's a TextInput in JS that sends { lineHeight: null } to C++. In Paper this was correctly handled as a default value, which just causes that property to not be set. In C++ in Fabric, it was being parsed incorrectly as 0 (because of incorrect defaults being passed into `convertRawProp`), causing the text to not be visible at all. The solution is to make sure that its default value is NaN, which is handled correctly, and causes the Text to render again.

Summary:
Refactors `Pressability` so that updates to the configuration are now explicitly committed using `configure()`.
Previously, the configuration was updated implicitly because `Pressability` accepted a series of functions whose closures capture values (e.g. `this.props`). Although these changes typically happen when component instances are "atomically" updated by React, it is not a guarantee. For example, arbitrary instance variables could be used to configure `Pressability`, and they could be muted at any time.
This change makes updates to the configuration of `Pressability` more predictable.

Summary:
Setting `padding` for Yoga node dirties it.
In the previous implementation, we did it for all newly cloned nodes. Now we do it only if State actually changes.
This is important because usually, SafeAreaView is a container node; that means that if some descendant of SafeAreaView changes its state, the recloning of all nodes down to root node will cause dirtying SafeAreaView and cause relayout if the whole subtree.
E.g., if we put ScrollView inside SafeAreaView without the fix, onScroll events will cause Yoga relayout (because ScrollView updates own state on debounced onScroll event).
