Skip activity animation if its display is animating

The display animation should cover entire screen. That avoids
mixing weird animations, such as reparenting other targets
to transition root, e.g. ActivityWrap.

Also change use display id to check in case there are multiple
displays. Suppose the changes are sorted by displays.
