Implement nativePerformanceNow to improve Profiler API results ( #27885 )
...
Summary:
When experimenting with React Profiler API (https://reactjs.org/docs/profiler.html ), I noticed that durations are integers without a debugger, but they are doubles with higher precision when debugger is attached. After digging into React Profiler code, I found out that it's using `performance.now()` to accumulate execution times of individual units of work. Since this method does not exist in React Native, it falls back to Javascript `Date`, leading to imprecise results.
This PR introduces `global.nativePerformanceNow` function which returns precise native time, and a very basic `performance` polyfill with `now` function.
This will greatly improve React Profiler API results, which is essential for profiling and benchmark tools.

## Changelog
[General] [Added] - Implement `nativePerformanceNow` and `performance.now()`
Pull Request resolved: https://github.com/facebook/react-native/pull/27885
Test Plan:
```
const initialTime = global.performance.now();
setTimeout(() => {
const newTime = global.performance.now();
console.warn('duration', newTime - initialTime);
}, 1000);
```

Remove @providesModule from all modules
...
Summary:
This PR removes the need for having the `providesModule` tags in all the modules in the repository.
It configures Flow, Jest and Metro to get the module names from the filenames (`Libraries/Animated/src/nodes/AnimatedInterpolation.js` => `AnimatedInterpolation`)
* Checked the Flow configuration by running flow on the project root (no errors):
```
yarn flow
```
* Checked the Jest configuration by running the tests with a clean cache:
```
yarn jest --clearCache && yarn test
```
* Checked the Metro configuration by starting the server with a clean cache and requesting some bundles:
```
yarn run start --reset-cache
curl 'localhost:8081/IntegrationTests/AccessibilityManagerTest.bundle?platform=android'
curl 'localhost:8081/Libraries/Alert/Alert.bundle?platform=ios'
```
[INTERNAL] [FEATURE] [All] - Removed providesModule from all modules and configured tools.

...
Summary:
A temporary React Native compatibility fix was added to React in commit [bba0d99](https://github.com/facebook/react/commit/bba0d992d8f4ecf9cf6677817a1218e7f48a8a77 ) and subsequently removed in commit [e612826](https://github.com/facebook/react/commit/e612826650ff68e73bff4d71db01fea8147ee1fd ). I noticed this while testing the React Native fiber renderer and attempting to use `Systrace`.
This commit updates React Native to no longer rely on the deprecated method and module.
PS I'm not sure if I should also update `ReactDebugTool` with this commit or wait for a subsequent sync script to update it. I haven't committed to this repo before. Please advise. 😄
