Add IPC support for gfx::ColorSpace

This structure, passed browser->renderer, is not necessarily an
ICC profile, so we shouldn't be passing it around as a raw ICC
profile.

This also adds the build targets that we'll be using for other color
related structures in the near future. In particular, we will be adding a
color space structure that cannot be a full ICC profile (because they
are heavy, and sending them renderer->browser would be unsafe).
