Fix split overlay by drag drop launch

Browse Source 
When drag drop launch, wms will use animation leash to do launch
transition, and reparent surface back and reset its position by
windows its configuration.
However, on split side we also set windows bounds in same time,
so in some race condition, wms side reset its position later and
use old configuration because we update it in same time then cause
task surface position wrong.
To fix this issue, we should apply windows bounds before we launch
the intent.

This CL also fix divider invisible issue when drag drop some specfic
app to active split screen caused by surface tanscation race too.

Fix: 227142506
Fix: 240638389
Test: manual
Test: pass existing tests.
