Synchronize display change with the Shell

This CL adds synchronization of applying of the window
container transaction with split-screen layout changes after
the display size change. This is needed for the unfold
animation to have the split screen layout ready
for the first frame of the unfold animation on foldable
devices.

The flow is similar to the display rotation synchonization,
now it is triggered on both physical display change and
rotation.

Bug: 204925795
Test: folding/unfolding, rotating with a split layout
  when Shell transitions enabled/disabled
