Add config to force display to transition to off after doze

Some display hardware can't do the transition from doze display states
to the on display state cleanly, so in order to hide any janky-ness of
the transition we force the display off and cover the screen with a
black surface. This lets us keep the screen black until SystemUI and the
display are both ready.
