Simplify SkColorSpace::MakeICC

Rather than restricting the supported ICC types in MakeICC, create any
ICC type that we support, and make the client reject them as necessary
by querying the SkColorSpace::Type.

Remove ICCTypeFlag and replace uses of it with SkColorSpace::Type.

This depends on a change in Chromium
(https://chromium-review.googlesource.com/c/chromium/src/+/741843).
Without that, this change will start allowing non-CMYK images to use
CMYK profiles.
