Reduce computing unused ChangeInfo in Transition

Originally, if the window container can not be animated or controlled
by remote, the intermediate ChangeInfo are just ignored during
calculating TransitionInfo. So they can be skipped earlier at creation.

For example when launching an activity in a task, there may be 10
ChangeInfo: 2 activities + Task + TaskDisplayArea + Display +
5 DisplayArea.

With this change, the 5 DisplayArea will be ignored (if their
organizers are not active): Root, WindowedMagnification,
HideDisplayCutout, OneHanded, and FullscreenMagnification.
Then in collect(), it no longer needs to traverse 30+ DisplayArea
for creating the intermediate parent ChangeInfo. That would also
speed up calculateTargets and calculateTransitionInfo because
less ChangeInfo to look up.

Also simplify getTopVisibleWallpaper (called in collect()) a bit by
eliminating unnecessary overhead of forAllWindows.
