Dispatch DisplayCutout from DisplayAdapter
Adds a config resource to configure the main display's cutout and
dispatches it from the LocalDisplayAdapter.
WindowManager's DisplayContent then transforms it to match the current
rotation.
Also fixes an issue in EmulatedDisplayCutout where the Path was never
reset and changes the color to black. Also fixes the RoundedCorners
overlay such that it can layout within the cutout area.
