Fix Launcher won't get split screen config changed after dismissed
When split screen was dismissed due to launching activity not supporting
split screen, it will reparent home task and update its bounds with two
different window container transactions.
When the home task was reparented without updating bounds, Launcher
won't refresh split screen state because it only updates split screen
config when there's orientation or screen size config changed. When the
home task's bounds was updated latter, it might not triggers
Activity#onConfigurationChanged due to the screen size changes didn't
cross the threshold after ag/13816978 and ag/13844692.
This merges reparent and reseting bounds transactions to make sure
Launcher updates split screen state properly after dismissed split with
not supporting split screen activity launched.
Fix: 188462404
Test: dismiss split screen by launcher activity not supporting
multiwindow, observed the split screen button shows properly in recent
panel.
