Remove SkImageInfoIsGammaCorrect, etc...

Our internal definition is (and will continue to be) that anything with
a color space is gamma correct. F16 is irrelevant (whether or not we
choose to support untagged F16). This makes these helpers less than
helpful, and lets us remove them from (public) API.

API change is just removal (of unused functions).
