Preempt recents animation if display is changed

This aligns the same behavior as [1]. Then the recents animation
can be finished, and the animating activity can be stopped with
a screenshot as the replacement. So the default rotation transition
animation can continue to play.

Bug: 271099935
Test: Enable rotation for launcher.
      Launch app and rotate to landscape and enter recents.
      Rotate to portrait.
      There should be a normal rotation animation
