Summary:
This adds https://github.com/mysticatea/abort-controller to polyfill [AbortController](https://developer.mozilla.org/en-US/docs/Web/API/AbortController). This is used to cancel requests when using `fetch`.
This also updates `event-target-shim` to 5.0 to make sure we only have one version of this dependency. This updates required adding a polyfill for `console.assert` which is used by the new version. I made one based on https://github.com/gskinner/console-polyfill/blob/master/console.js#L74.
The polyfill is very small, especially since we already use `event-target-shim` so I think it makes sense to include in core.
Depends on #24418 so that the fetch polyfill supports the `signal` parameter.
Fixes#18115

Closes: https://github.com/facebook/react-native/issues/24016
React Native 0.57 introduced cross-platform `accessibilityRole` and `accessibilityStates` props in order to replace `accessibilityComponentType` (for android) and `accessibilityTraits` (for iOS). With #24095 `accessibilityRole` and `accessibilityStates` will increase, receiving more options, which seems to be a good moment to remove deprecated props.
Remove deprecated `accessibilityComponentType` and `accessibilityTraits` props.

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.

Summary:
There are cases where native modules will try to reference other native modules during startup, which can causes a deadlock on `RCTModuleData::_instanceLock`.
My system was in a state where the deadlock would repro 100% so I could actually debug it a bit, but really this whole system is very fragile and needs to die in a fire.
I tried a recursive lock and it was not sufficient - there are definitely issues with multiple threads invoking at the same time and then calling `RCTUnsafeExecuteOnMainQueueSync`...

Summary:
This diff replaces all MountItem classes with a bunch of static C functions that do the same job as classes did.
Seems, originally we overestimated the complexity of MountItem classes and that they ended up being notably trivial. Now, maintaining that even longer would mean paying for abstractions and allocations that we don't really need and writing a lot of tedious code.
Besides that, the one particular change that will be introduced in the coming diffs is not particularly fit very well in the existing class-based model.
This change also should save us many hundreds of allocations and atomic counters bumps, so maybe we can get a millisecond-or-two win.
This diff does not introduce any practical behavioral/logical changes in the mounting layer.

Summary:
Motivation is following - I'm sure many people encountered this because it has been like this for a long time.
1 . you're developing something on android, HMR and dev mode is enabled
2 . you go to dev settings, you disable dev mode because you want to see how something behaves
3 . you reload the app because that's what is required for the change to take effect
4 . you wait for the bundle to be compiled and served, and when that is done, you get an error message about HMR not being a registered callable module - because HMR is not available when `__DEV__ === false` (todo screenshot)
this fixes the described case by checking if HMR is enabled and dev mode disabled when reloading (step 3) and disables HMR in that case.
this also fixes the case when dev mode is disabled and without knowing it, you try to enable HRM (will enable both dev hmr and dev mode).

Summary:
There is a problem rendering text shadows on iOS. If the offset of the text shadow is `{width:0,height:0}`, the shadow does not display. This prevents you from representing a light directly above the text. This occurs because a text shadow only renders if the offset is a non-zero CGRect `{width:0,height:0}`.
My change checks `textShadowRadius` instead. If `textShadowRadius` is not nan then the user is rendering a text shadow. There are no situations to render a shadow without `textShadowRadius` making it a good variable to check.
This PR fixes this stale issue: https://github.com/facebook/react-native/issues/17277

It allows apps to easily download fonts from online providers, but also use of various font weights other than normal and bold, like medium. So it deprecated APIs for asset fonts, and should be removed in the future.
Advantages:
- Just copy font files in res/font and use it specifying filename (without extension) in fontFamily
- Define custom font-family using XML file (in res/font) and font files, it may have many weights and styles. See PR for example.
- Define configuration to download fonts from online font providers, and use it.

This allows an unsupported component to be rendered as a "unimplemented view" for better visualization of which component is missing. It is off by default, but configurable in the component factory.
For now, the layout simply follows regular <View />, which means the width/height etc is based on the react component styling. The side effect is that components with 0 height/width won't show up at all.

Summary:
For props that expects a struct/object value, like scrollView's contentInset, not all keys may be present. For example:
```
<ScrollView ... contentInset={{top: 10}} />
```
In this example, `left`, `bottom`, and `right` should just default to 0 (or whatever the default is in the platform). Before this fix, an exception occured when calling `fromRawValue()` because it is assuming all 4 keys are present in the prop bag. However, only `top` key was present in this example.
To fix this, we have to loop through the available keys in the prop bag, then assign the values accordingly.

Summary:
In the case where the first rootView we load enables Fabric, the UIManagerBinding ended up calling AppRegistry (JS) too early, before the bridge was fully ready. This means AppRegistry wasn't set up yet, causing redbox.
To fix this, RuntimeExecutor impl should ask the bridge to queue the callback instead of asking the MessageQueueThread directly. MessageQueueThread only works well IFF the bridge is alive, but it has no knowledge about whether the bridge is alive or not. To support this, we add `invokeAsync` impl to the RCTCxxBridge.

The root cause comes down to the fact that historically `-DFOO=0` and `-DFOO=1` patterns have been used when it comes to preprocessor definitions and various engineers use `#ifdef FOO` and `#if FOO` interchangeably. That results in an incorrect pattern because the real evaluation is following:
- `FOO` not defined: `#if FOO` = `FALSE`, `#ifdef FOO` = `FALSE`.
- `-DFOO=0`: `#if FOO` = `FALSE`, `#ifdef FOO` = `TRUE`.
- `-DFOO=1`: `#if FOO` = `TRUE`, `#ifdef FOO` = `TRUE`.
