Add video_off_hdmi option to power down HDMI on idle timeout (#1110)

Browse Source 
When video_off_hdmi=1 is set in MiSTer.ini, the ADV7513 HDMI
transmitter is powered down via I2C when the video_off timeout
expires, allowing the connected monitor to enter sleep mode.
HDMI is restored when user activity is detected (OSD opens).
