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 gets us on the latest Prettier 2.x:

Notably, this adds support for TypeScript 3.8,
which introduces new syntax, such as `import type`.

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.
See the umbrella issue at https://github.com/facebook/react-native/issues/24316 for more detail.

Summary:
We don't want to remove the last queue from the stack, it should just have no tasks in it.

Summary:
Returns a promise-like object with a new cancel function that will dig through the queue
and remove relevant tasks before they are executed. Handy when tasks are scheduled in react
components but should be cleaned up in unmount.

Summary:
Default behavior should be unchanged.
If we queue up a bunch of expensive tasks during an interaction, the default
`InteractionManager` behavior would execute them all in one synchronous loop at
the end the JS event loop via one `setImmediate` call, blocking the JS thread
the entire time.
The `setDeadline` addition in this diff enables an option to only execute tasks
until the `eventLoopRunningTime` is hit (added to MessageQueue/BatchedBridge),
allowing the queue execution to be paused if an interaction starts in between
tasks, making the app more responsive.
Additionally, if a task ends up generating a bunch of additional tasks
asynchronously, the previous implementation would execute these new tasks after
already scheduled tasks. This is often fine, but I want it to fully resolve
async tasks and all their dependencies before making progress in the rest of the
queue, so I added support for `type PromiseTask = {gen: () => Promise}` to do
just this. It works by building a stack of queues each time a `PromiseTask` is
started, and pops them off the stack once they are resolved and the queues are
processed.
I also pulled all of the actual queue logic out of `InteractionManager` and into
a new `TaskQueue` class to isolate concerns a bit.
