Enable new color functions from CSS Color 4 (#30752)

I will need to do most of the work anyways during the style updates,
so by enabling this it will be easier to detect mistakes.

Also, canvas colors are now parsed as <color>, precisely to support
these new features. This is according to the HTML spec:
