8E6C: Print a message
The six byte header holds the attribute byte, the back buffer destination and the screen attribute address; the NUL terminated string follows it and is rendered by draw_string_with_style. The pointer returned is the byte after the NUL, so callers can chain one message block onto the next.
Used by the routines at load_stage, attract_mode_48k, draw_pregame, draw_overlay_messages and load_stage_128k.
