We may not need this to be a public API if/when we integrate this with
serialization/deserialization.

1. should be const
2. no need to mention "serialization" in the comment imho
3. could make it private for now, but somehow this seems sensible and so I'm
fine if its public

Done.
Removed.
Moved to SkColorSpace_Base.  Still public so we can test.
