[wpiunits] Add Measure.per overloads for all known unit types (#7699)

Instead of only providing per(TimeUnit)

Useful for making conversion factors easier, eg `Inches.of(10).per(Rotation)` vs `Inches.of(10).per(Rotation.one())`

Update VelocityUnit.one() and VelocityUnit.zero() to return Velocity objects instead of generic Measure<? extends VelocityUnit<D>>; VelocityUnit is final, so the wildcard generic is unnecessary, and this makes the generated `per` functions possible for this type
