Reduce unnecessary redraw when unlocking
The visible windows may be drawn earlier then the
timing to start requesting draw. And the starting
window should be used to cover the drawing time of
main window.
This may reduce hundreds of milliseconds of unlock
latency on slower devices.
Bug: 139522754
Bug: 140811348
Test: atest ActivityVisibilityTests
WindowStateTests#testRequestDrawIfNeeded
Test: Use biometrics to unlock device with log
WM_DEBUG_SCREEN_ON and WM_DEBUG_DRAW enabled.
There shouldn't have multiple finishDrawingWindow
from the same window.
