color: Add unit test to ensure sRGB SkColorSpaces match

It turns out that Skia does fuzzy comparision for gamma and gamut
internally. Add tests to be emphatic about this, since we don't want to
promote layers to non-sRGB rendering just because they have an image
that is tagged with an sRGB color space.

There's still a TODO for this in gfx::ColorSpace, which we should eventually get
to (the gfx::ColorSpace one, cause the Skia one is pretty stringent ... see
https://cs.chromium.org/chromium/src/third_party/skia/src/core/SkColorSpacePr...).
