Implement launch bounds logic in Android (3/3)

This CL introduces persistence to launch bounds logic. It also wires up
the following state changes and persister:
1) freeform resizing;
2) windowing mode change;
3) display change;
4) task closing.

We may still need to persist immersive mode, but that needs further
discussion.

Changed launch bounds modifier a bit so that it won't launch tasks that
are completely out of the new display or conflict to existing tasks.

Bug: 113252871
Test: Manual tests on that freeform launch bounds are persisted across
reboots.
