  [css-color] Implement color-layers() (without blend mode support)
https://bugs.webkit.org/show_bug.cgi?id=277837
rdar://133499954

Reviewed by Sam Weinig.

This implements rendering & syntax for color-layers(<color>#) where the list of colors is ordered from top to bottom (like background layers).

https://drafts.csswg.org/css-color-6/#color-layers

Preliminary piping for the optional <blend-mode> parameter is also added, though the parsing code is commented out until rendering is implemented.
