Handle some Recents finish corner cases
This handles a couple of the corner-cases around recents transition
and "internal" live-tile activity transitions.
The first is that the change detection will check if a going-invisble
activity is already invisible. This way, if the finish transaction,
makes launcher invisible, the activity transition will ignore it
instead of trying to animate an already-invisible activity. This
works because we defer commitVisibility so that we can animate with
visible content.
The second is that the finish operation for transient-launch will
not commitVisibility for any activities under a transient-hide task
if that task didn't actually hide. This way it won't prematurely
destroy activity content that is still visible/animating.
Bug: 276755325
Test: Tap on activity-launch icons through gesture bar and observe
fewer flickers (this doesn't solve all of them though). Can
look at logs to verify that the flickers are not from these
sources.
