Luna Wei 4ca089f94c Simplify Coalescing Key ...

Summary:
Changelog: [Internal]
Stop using `TouchEventCoalescingKeyHelper` for tracking and stop making the distinction between traditional touch events (down, up, move) vs hover only events. The only events that currently coalesce are `onpointermove` events. This change uses just one counter now that we increment whenever some non-move event is fired.

Let me know if there's a simpler way to ensure counter doesn't overflow.
This change also ensures we're overriding `getCoalescingKey` which isn't used by Fabric but for old event emitter it might be (which we use for native animations). Part of that requires the `coalescingKey` to be a short so updated to that.

There was also a bug where I forgot to pass `mLastButtonState` to one of the dispatch calls. Will be wrokign on refactor so its less argument soup.
