Change MIDI velocity implementation to allow direct control of velocity value (#9940)
* Initial changes to expose "real" MIDI velocity

* Change MI_VELU and MI_VELD to fit new logic

* Apply cleanups from fauxpark's review

my bad on the errant whitespace and else {} placements

* Slight changes to MI_VELD to match values when velocity is falling to when it is rising

* Add keycode MI_VEL_0

* Update compute_velocity() to handle MI_VEL_0

* Store velocity as 7 bits to hard cap value at 127
