Moved named common transfer functions and gamuts to constexpr values in SkColorSpace.h, in SkNamedTransferFn and SkNamedGamut namespaces. Converted nearly all SkColorSpace::MakeRGB calls within Skia to use the new factory with the named values. Multiple clients want a way to extract named transfer function and gamut - this still doesn't provide that, but this may be a better path forward for honestly advertising how SkColorSpace works internally.
