Added kSRGBLinear_Named color space, along with tests

Gradients (and other shaders) are going to end up serializing this
particular color space very frequently, so we want a shorthand way of
writing it out. I think it's also helpful to have a clearer way of
creating it (vs. NewNamed(kSRGB_Named)->makeLinearGamma()).

Might be interesting to comment on why this is interesting/commonly used to
justify that it belongs here.
