Implement default exit animation for splash screen.(9/N) 

Implement default exit animation on the view of splash screen, there
will be a two layers switch happen when playing exit animation. For
the detail please reference
go/improved_app_launch_animations and go/app-startup

Note: For this version we skip shift-up animation, need to fix the
flicker test so we can enable it.
Note2: Fix the possible missing splash screen view issue, but could
make the first window draw slower, keep tracking.

Bug: 73289295
Test: build/flash
Test: check splash screen starting window.
Test: atest StartingSurfaceDrawerTests ShellTaskOrganizerTests
WindowOrganizerTests SplashscreenTests
