Add Face Scanning anim
Render the face scanning animation and the camera
protection in FaceScanningOverlay, a SW layer.
Implementation notes:
* The face scanning animation cannot be rendered
in the HW layer because it requires color.
* We cannot render the face scanning and camera
protection overlays in different layers (HW and SW),
because then they are difficult to coordinate.
=> Therefore, we render both the camera + face
scanning animation in a SW layer together.
Test: atest ScreenDecorationsTest
Test: debug mode (adb shell setprop debug.screenshot_rounded_corners 1)
Test: enable color inversion, see camera protection is still black
Test: enable/disable face scanning feature and see that camera
protection and face scanning anim works. Also test privacy dot
indicator view still shows appropriately with and w/o the face
scanning animation
Test: Check systemui dumpsys for view visibilities. Face
scanning overlay should NOT be visible unless playing
its animation.
