Summary:
React Native's TS definitions are currently mostly stored in one monolithic file. This change splits the definitions up to correspond to the source files they came from, and are placed next to the source files. I think this should help inform, and make it easy to update the TS declarations when touching the Flow file.
I noticed as part of the change that the typings have not yet removed many APIs that were removed from RN. This is bad, since it means using the removed/non-functional API doesn't cause typechecker errors. Locating typings next to source should prevent that from being able to happen.
The organization here means individual TS declarations can declare what will be in the RN entrypoint, which is a little confusing. Seems like a good potential next refactor, beyond the literal translation I did.

[General][Changed] - Place TS Declarations Alongside Source Files

Summary:
Jest 27 [flips defaults](https://jestjs.io/blog/2021/05/25/jest-27#flipping-defaults), making "modern" fake timers (ie, `sinonjs/fake-timers`) the default, over "legacy", which we currently use.
We're not quite ready for modern timers yet, partly due to Promise polyfills (https://github.com/facebook/react-native/pull/34659), and also some internal issues with specific tests.
This makes our use of legacy timers explicit in preparation for an update to Jest. A switch to modern timers may follow later.

Summary:
Deprecates the nonstandard `Promise.prototype.done` method. This also removes one call site within React Native itself that relied on this method.
As part of this we are also removing React Native's custom Flow definition for `Promise` in favour of the standard one built into Flow. This will flag uses of `done` as type errors for anyone using the default app template's `.flowconfig`.
In a future release of React Native, we will remove the `done` method from the built-in `Promise` polyfill.
Changelog:
[General][Deprecated] - Deprecate the Promise.prototype.done method and log a warning when it's called in development.

Summary:
This pull request fixes a potential `TypeError` in TaskQueue.js, that happens if a promise is added to the task queue, which is cancelled between the promise starting and resolving.
The exact error this resolves is
```js
TypeError: TaskQueue: Error resolving Promise in task gen1: Cannot set property ‘popable’ of undefined
167 | queueStackSize: this._queueStack.length,
168 | });
> 169 | this._queueStack[stackIdx].popable = true;
| ^
170 | this.hasTasksToProcess() && this._onMoreTasks();
171 | })
172 | .catch(ex => {
at Libraries/Interaction/TaskQueue.js:169:46
```
This specific error was also reported in https://github.com/facebook/react-native/issues/16321
## Changelog
[General] [Fixed] - Prevent TypeError in TaskQueue when cancelling a started but not resolved promise.
Pull Request resolved: https://github.com/facebook/react-native/pull/29969
Test Plan:
The added test demonstrates the error, if run without the fixed applied to TaskQueue.js.
This is a race condition error, so is difficult to replicate!

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.
