Nick Chameyev 14b4f9edcc [Unfold animation] Do not preemptively start the animation if it has run already
Currently if we open an app, unfold the device and then go to home
screen we will start the unfold animation preemptively in Launcher
because Launcher activity will receive updated configuration change
(where isTablet = true) only after going back to home screen, not
when unfolding the device.

This causes a problem because SystemUI won't send the unfold animation
events after going back home as the animation has already run, so we
end up with wrongly started animation in Launcher.

This CL fixes the issues by checking if SystemUI has finished the
animation (or if it is currently running) to avoid preemptive animation
start in this case. This is done by subscribing to the original
unfold transition progress provider which emits progress events
sent through IPC from SystemUI.

Bug: 285150685
Bug: 293131586
Test: open an app on folded screen, unfold, go to home screen =>
  check that icons are not squished
Test: fold/unfold when launcher is open
