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:
Previously, `InteractionManager` was baked in at the lowest level to all touches via `ResponderEventPlugin`,
which meant that any time a finger was touching the screen, `InteractionManager` would be locked. This included while
doing 100% native scrolls, and thus would block progress from Relay, Incremental, or anything else scheduling events
through `InteractionManager`.
This diff switches to only bake it into `PanResponder` (and it remains hooked into `Animated` as before) which are the
main two cases where we need 60fps JS execution and want to queue up slower tasks.
This is done with a reusable higher-order-responder `InteractionManager.createResponderClass`.
Depends on FYI https://github.com/facebook/react/pull/6587, https://github.com/facebook/react/pull/6584

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.

Summary: In accordance with the unwritten rule that any API that takes a callback should also return a promise, I've changed `InteractionManager.runAfterInteractions()` to do just that.
```js
InteractionManager.runAfterInteractions(() => {
...
});
```
can become
```js
InteractionManager.runAfterInteractions().then(() => {
...
});
```
(but doesn't have to). Most importantly, though, this change enables code like
```js
doSomeUIStuff();
await InteractionManager.runAfterInteractions();
doSomeNonUIStuff();
```
which is nice.
Note: Because returning a `Promise` means the callback argument is now optional, the behaviour of the API is slightly changed, though not in a backwards-incompatible way (unless a consumer is in some way relying on the exception, but that would be insane).
