Update face scanning anim, fix visibility bugs

- The face scanning view visibility should
always be INVISIBLE if the face scanning anim isn't
running
- The face scanning view height should never
take up the entire screen (there was an issue where the
face sensor location  was being requested before the display
resolutiong/scale size was correct, so the face height location
was reporting INFINITY instead of the actual location
of the face camera sensor)
- Face scanning anim needs to handle resolution changes

Test: Settings > Display > Screen resolution
Test: Check hierarchy viewer for size of the view when
the face scanning animation is running, check different
orientations
Test: Check sysui dumpsys when face scanning animation
is NOT showing (view should be visible on reboot)
Test: atest ScreenDecorationsTest
