1. Prevent updating split layout twice during rotation with
configuration changed. If the only difference is orientation, it
means we've handled bounds changes for rotation before, the only
thing thing left is to make sure divider bar will be rendered
with proper resources that matching with the new orientation.
2. When handling child task changes, make sure to also update crop if
it's not sharing the same bounds with its parent.
3. Also exclude adjusting bounds of tasks created-by-organizer while
display changed, since the organizer created them should handle
that instead. This is needed to prevent their bounds being rotated
twice in organizer and wm-core.
