boards: simulator: Add basic mute simulation
Currently the simulator shows redraw artifacts that are concealed
on the real device by using display on/off. We can improve this by
avoiding the refresh when the display is off. This does not match
the behaviour of the real hardware (which goes dark during transitions)
but does make the simulator feel much more comfortable to use.
