Reland slow gesture callback handling

Now that b/329324086 has been fixed, we can be more certain that launcher always gets a signal to clean up from WM.

- Relanding original fix for b/285636175 with some additional error checking
- We will now check whether the recents animation start is pending on ACTION_UP
- We will now block entire swipes to prevent sending additional inputs an input consumer while the recents animation start is pending
- We will now only stop blocking inputs on ACTION_DOWN
