Summary:
RCTSurface instance represents React Native-powered piece of a user interface
which can be a full-screen app, separate modal view controller,
or even small widget. It is called "Surface".
The RCTSurface instance is completely thread-safe by design;
it can be created on any thread, and any its method can be called from
any thread (if the opposite is not mentioned explicitly).
The primary goals of the RCTSurface are:
- ability to measure and layout the surface in a thread-safe and synchronous manner;
- ability to create a UIView instance on demand (later);
- ability to communicate the current stage of the surface granularly.

While building a React Native application, I've come across the use case of wanting to set a specific locale for DatePickers irrespective of the users OS region setting. Since this is a feature available to native DatePicker components, I think it would be helpful to expose this in React Native as well.
Testing can be done by passing a `locale` prop to a DatePickerIOS. Example:
```
<DatePickerIOS
date={this.state.date}
mode="date"
locale="fr_FR"
onDateChange={date => this.setState({ date: date })}
/>
```

Summary:
This provides a way to customize the return type of a sync exported method, instead of just using `id`.
```
RCT_EXPORT_SYNCHRONOUS_TYPED_METHOD(NSString *, sync1:(NSString *)x)
{
return @"hello";
}
```
The return type needs to be a sub type of `id` - so scalars like `double` won't work (the bridge will crash).

Summary:
- The version check that ensures the JS and native versions match is now in its own module for two reasons: it is easier to test and it allows react-native-windows to override just this module to implement its own version check (ex: more advanced checks for RNW-specific code).
- Added unit tests for the version checking to specify its behavior more clearly, including parity between dev and prod to avoid prod-only behavior and mitigate SEVs.
- Prefixed the Obj-C `#define` with `RCT_` to conform with other RN globals.

Summary:
Basic implementation of the proposal in #15271
Note that this should not affect facebook internally since they are not using OSS releases.
Points to consider:
- How strict should the version match be, right now I just match exact versions.
- Wasn't able to use haste for ReactNativeVersion because I was getting duplicate module provider caused by the template file in scripts/versiontemplates. I tried adding the scripts folder to modulePathIgnorePatterns in package.json but that didn't help.
- Redscreen vs. warning, I think warning is useless because if the app crashes you won't have time to see the warning.
- Should the check and native modules be __DEV__ only?
**Test plan**
Tested that it works when version match and that it redscreens when versions don't before getting other errors on Android and iOS.

Summary:
Remove fallback logic.
It is hard to test whether a bundle is good or bad on device, since it does the fallback, remove the fallback logic now.

Summary:
This is revert of revert of https://github.com/facebook/react-native/pull/15542
WITHOUT default RCT_MAIN_THREAD_WATCH_DOG_THRESHOLD value. So, it makes it completly opt-in feature.
When code blocks the UI thread for too long, it's a bad sign because this can prevent the app from remaining responsive. This change helps detect such responsiveness issues by warning when a React method executes on the UI thread longer than some threshold.

**Test Plan**
Changed AppState's getCurrentAppState method to sleep for 500 ms and verified that a warning was emitted:
```

Summary:
(This diff was decoupled from D4983054 which landing was quite delayed.)
`RCTUnsafeExecuteOnMainQueueOnceSync()` synchronously executes a block once, on main queue.
I found that our old implementation of `RCTScreenScale()` causes deadlock when it is called from main and background thread simultaneously.
After I implemented my own solution I googled this issue and found an article by Ben Alpert with this awesome helper:
https://benalpert.com/2014/04/02/dispatch-once-initialization-on-the-main-thread.html
So, I found it super useful and borrowed it.

Summary:
This shows progress for the download of the JS bundle (different from the packager transform progress that we show already). This is useful especially when loading the JS bundle from a remote source or when developing on device (on simulator + localhost it pretty much just downloads instantly). This will be nice for the expo client since all bundles are loaded over the network and can take several seconds to load.
This depends on https://github.com/facebook/metro-bundler/pull/28 to work but won't crash or anything without it, it just won't show the progress percentage.
**Test plan**
Tested that bundle download progress is shown properly in RNTester on both localhost + simulator and on real device with network conditionner to simulate a slow loading bundle.
Tested that it doesn't cause issues if the packager doesn't send the Content-Length header.
