surfaceflinger: Add clientDrawnCornerRadius and clientDrawnShadowLength layer properties

Modify RoundedCornerState and ShadowSettings to account for client drawn corners and shadows. When equal to the requested values, SurfaceFlinger will not draw corners and shadows for the layer.

Bug: 375624570
Flag: com.android.window.flags.ignore_corner_radius_and_shadows
Test: atest SurfaceFlinger_test; manual test - PIP, freeform window, recents, app launch
