Input: Add and document BTN_GRIP*

Browse Source 
Many controllers these days have started including grip buttons. As
there has been no particular assigned BTN_* constants for these, they've
been haphazardly assigned to BTN_TRIGGER_HAPPY*. Unfortunately, the
assignment of these has varied significantly between drivers.

Add and document new constants for these grip buttons.
