Input: Add vertical and horizontal scroll axes

Browse Source 
To be used for smooth scrolling with future driver APIs, replacing
Rel Vert Wheel and Rel Horiz Wheel axes, which have not been used in any
open driver to date.

Combined with double-granularity ValuatorMasks, these axes allow for
fine-grained scroll data to be sent to clients.  Future commits allow
drivers to post these scroll axes to
QueuePointerEvents/GetPointerEvents, which take care of emulating legacy
scroll button events.
