Add destination color space to AsFPArgs. Eliminates last XFORMTODO.

This is going to be needed in many more places as I finish connecting the
dots. Even better - I'd like to switch to a world where SkColorSpace !=
nullptr is the only signal we use for gamma-correct rendering, so I can
eliminate SkSourceGammaTreatment and SkSurfaceProps::isGammaCorrect.
