Summary:
Registries, providers, providers of registries, registres of providers. All that can be really confusing, but that represents best the constraints and desires that we have:
* We need to be able to register components on-the-fly (so we need a mechanism that will propagate changes);
* We don't want to register ComponentDescriptors separately from ComponentView classes;
* C++ not always gives us abstractions that we want (e.g. pointers to constructors).
After the change, we can remove the whole Buck target that has a bunch of handwritten boilerplate code.
There is a still room for polish and removing some concepts, types or classes but this diff is already huge.

Summary:
ComponentDescriptorProvider represents unified way to create a particular descriptor.
Now all ComponentViews (which support RCTComponentViewProtocol) expose a `ComponentDescriptorProvider` which will allow creating and registering ComponentDescriptor instances for all visual components automatically as a part of ComponentView registration process.
Don't panic, everything is still being as explicit as it always was, no magic involved; we just will have only one registration step instead of two parallel.
That also opens a way to register components on the fly.

This diff fixes the reconnect logic with the metro websockets which is causing the app to not re-connect when metro crashes. To demonstrate the issue, consider the following video:
{F156029086}
On the left we have metro, on the right is the xcode console with some logging to show the reconnecting phase. When we kill the metro server you can see the app tries to reconnect once and that's it - when metro is started back up, you can see the notification that there are no apps running and can also see that cmd+opt+r doesn't work anymore
I updated the logic to optimistically start the connection and if it's still unavailable to retry again after the timeout

Summary:
React Native has a `NativeModule` to manipulate programmatically the dev menu options (live reload, hot reload, remote debugging, etc), called [`DevSettings`](https://github.com/facebook/react-native/blob/master/React/Modules/RCTDevSettings.mm#L120). However this module is only available for iOS.
This PR brings the same `DevSettings` for Android, making it a cross-platform NativeModule.
Motivation: Right now if your app needs to programmatically reload RN, one option is to install [`react-native-restart`](https://www.npmjs.com/package/react-native-restart). It's a tiny dependency, but it's annoying to have to install it, while the code to do so is inside RN codebase. According to NPM, react-native-restart has ~12k weekly downloads, shows it's a recurring feature for many apps (my case).
Thus making `NativeModules.DevSettings` is a small increment in the codebase, just exposing the dev menu methods, to improve the Development Experience
[Android] [Added] - Add DevSetting native module (making it cross-platform)
With expection of `setIsShakeToShowDevMenuEnabled`, the following methods will be available for both platforms:
* reload
* setHotLoadingEnabled
* setIsDebuggingRemotely
* setIsShakeToShowDevMenuEnabled
* setLiveReloadEnabled
* setProfilingEnabled
* toggleElementInspector

Summary:
If you call into a Java method (from C++ using JNI) that raises an exception, the JNI call won't actually raise a C++ error. Instead, the `JNIEnv` will record the pending Java exception and the C++ will continue executing as normal. This is bad because the next time you call into JNI, the app will actually crash, unless you explicitly cleared the exception using `JNIEnv::ExceptionClear()` before the JNI call.
With respect to TurboModules, we need to make sure that RedBoxes show up whenever a native methods raise an exception. We also don't want the app to crash when a JNI method call fails because of a raised exception. Therefore, in this diff, I raise a C++ exception if `JNIEnv::ExceptionCheck()` is true.

Would like feedback from the community as this may not be the best solution for all
I would like to restrict (or paginate) the fling of a horizontal ScrollView when `snapToInterval` is set. This is not currently possible with `pagingEnabled`, since the pagination works only when items are the entire width of the ScrollView.
This implementation simply restricts the predicted `targetOffset` found from the `x` velocity and replaces it with the offset when the pan gesture ended.
To get pagination working, I may paginate based on the interval by calculating the offset delta from the beginning of the gesture to current offset and restricting the scrolling behavior to the `snapToInterval`. If this is preferred, I can update this PR or make a new one, but wanted to start a discussion since it seems like there are many in the community that would like this feature #21302 .

Summary:
For a small subset of Android devices, the following line of code caused the device to crash
```
output.transferFrom(input, 0, Long.MAX_VALUE);
```
According to the [Java docs](https://docs.oracle.com/javase/1.5.0/docs/api/java/nio/channels/FileChannel.html), this is what the function does.
> Transfers bytes into this channel's file from the given readable byte channel.
An attempt is made to read up to count bytes from the source channel and write them to this channel's file starting at the given position. An invocation of this method may or may not transfer all of the requested bytes; whether or not it does so depends upon the natures and states of the channels. Fewer than the requested number of bytes will be transferred if the source channel has fewer than count bytes remaining, or if the source channel is non-blocking and has fewer than count bytes immediately available in its input buffer.
Hence, using `Long.MAX_VALUE` seemed to be the standard way to transfer all bytes from one channel to the other.
However, it appeared that for some reason on a subset of old Android devices, the device tries to allocate `count` bytes of memory before transferring the bytes. Obviously, this caused a crash because no device has that much memory. This was fixed transferring bytes using a 1MB buffer.

The polyfill is very small, especially since we already use `event-target-shim` so I think it makes sense to include in core.

Summary:
`[RCTBridge setUp]` and `[RCTBridge invalidate]` execute asynchronously and concurrently. Therefore, it's not safe to call one method after the other, as we do in `[RCTBridge reload]`.
In this test, we create a bridge, and immediately reload it. Initializing the bridge causes the JS bundle to execute. Invalidating the bridge causes the jsThread to be terminated. If circumstances are correct, we could end up trying to executing the JS bundle after the jsThread has been terminated, which can lead to these assertions being triggered:
1. `RCTAssert(_jsThread, @"This method must not be called before the JS thread is created");` in `ensureOnJavaScriptThread:`.
2. `RCTAssert(_jsMessageThread != nullptr, @"Cannot invoke completion without jsMessageThread");` in `enqueueApplicationScript:url:onComplete:`.
```
- (void)testUnderlyingBridgeIsDeallocated
{
RCTBridge *bridge;
__weak id batchedBridge;
autoreleasepool {
bridge = [[RCTBridge alloc] initWithBundleURL:_bundleURL moduleProvider:nil launchOptions:nil];
batchedBridge = bridge.batchedBridge;
XCTAssertTrue([batchedBridge isValid], @"RCTBridge impl should be valid");
[bridge reload];
}
RCT_RUN_RUNLOOP_WHILE(batchedBridge != nil)
XCTAssertNotNil(bridge, @"RCTBridge should not have been deallocated");
XCTAssertNil(batchedBridge, @"RCTBridge impl should have been deallocated");
// Wait to complete the test until the new bridge impl is also deallocated
autoreleasepool {
batchedBridge = bridge.batchedBridge;
[bridge invalidate];
bridge = nil;
}
RCT_RUN_RUNLOOP_WHILE(batchedBridge != nil);
XCTAssertNil(batchedBridge);
}
```
To verify that this race is real, patch: P62410422. This adds an artificial delay in the `[RCTCxxBridge start]` method, which makes it so that the bridge is invalidated and the js thread is destroyed before we start executing the jsBundle.
I think a proper solution to this problem would require some bit of restructuring of `[RCTCxxBridge invalidate]` and `[RCTCxxBridge start]` to either:
1. Force `[RCTCxxBridge invalidate]` to wait for `[RCTCxxBridge start]` to complete and vice versa.
2. Make it safe to interleave execution of `[RCTCxxBridge start]` and `[RCTCxxBridge invalidate]`.
I tried the first approach using two semaphores: `_startSem(1)` and `_invalidateSem(0)`. When you start executing the code inside `[RCTCxxBridge start]`, you `semWait(_startSem)`. When you stop executing the code inside `[RCTCxxBridge start]` (which could happen in another thread at some later point in time), you `semSignal(_invalidateSem)`. Likewise, when you start executing `[RCTCxxBridge invalidate]`, you `semWait(_invalidateSem)` and when you stop executing the code inside `[RCTCxxBridge invalidate]` you `semSignal(_startSem)`. This way, invalidates always wait for starts to finish, and starts always wait for invalidates to finish. But considering all the concurrency involved in these methods, this is hard to get right.
The second approach seems possible. You could keep locks for the shared data, and create critical sections whever you want to access that data. I didn't actually try to implement this approach though.
Given that we're going to elminate the Bridge anyway, and that this race condition practically only occurs when you reload imediately after initializing the bridge (which can only really be done programmatically), I think it's fine to just disable the test for now. One other thing I considered was making the current thread sleep for some time after we created the bridge in the test. The reason why I'm hesitant to implement this approach is that it would slow down the execution of the test suite and still wouldn't guarantee that we don't hit this race condition. Ultimately, our infra might end up disabling these tests again.
