Use boundsChangeTransaction to improve split-screen enter/exit

Uses applySyncTransaction to synchronize all the surface
updates during split-screen enter/exit.

In Divider, all syncTransactions are serialized and runnables
can be posted to operate on the returned transactions so
they happen all at once.

This also required adding a "merge" functionality on
WindowContainerTransactions to handle racing between rotation
and other in-flight sync transactions (because they are
serialized, sometimes they got delayed).

Bug: 153579514
Test: Enter/exit split-screen and observe no flickers
