collapse parametric_{r,g,b} into parametric, remove _a and gamma_dst

parametric_a and gamma_dst were unused outside of unit tests.

In all other cases, we always use parametric_{r,g,b} together
and always pass them the same argument.  So we can collapse
them into a single stage like gamma and to/from_srgb.
