[qcms] Add API to get parametric gamma curve data

qcms_profile_get_parametric_curve returns the parameter data
of a parametric gamma (TRC) curve. Caller must pass in the
color channel to retrieve the corresponding channel TRC.

At most 7 float parameters are returned in the user-provided
array. The return value is the number of parameters, or 0
if the profile curve is not parametric or is invalid.
