Workaround to ensure we cancel the recents animation prior to starting home

- It is possible for the call from SystemUI to cancel the recents animation
  to be processed and handled after the virtual key has been processed in
  PhoneWindowManager. This causes a misordering in which the canceling of
  the Recents animation clears the pending start activity remote animation
  (which is waiting for app transition ready).

  Instead, move the canceling of the Recents animation to PhoneWindowManager
  where the nav button is handled, to ensure that we cancel the animation
  on the same thread before we start the activity.

Bug: 73188263
Test: Only able to reproduce so far artificially, which points to this
      misordering
