system_api: Add SetBacklightBrightnessRequest powerd proto.
Add a SetBacklightBrightnessRequest protocol message that
Chrome will send to powerd via SetScreenBrightnessPercent
D-Bus method calls. These calls currently send raw D-Bus
arguments, but a new "cause" argument is needed.
Also add a new "MODEL" enum value to
BacklightBrightnessChange's "cause" enum.
