Log Message:
-----------
Add support for the palette-mix() function
https://bugs.webkit.org/show_bug.cgi?id=322450
Reviewed by Antti Koivisto.
Adds parsing and model support for the palette-mix() function
behind new preference CSSFontPaletteMixFunctionEnabled.
Also adds a strong type for ColorInterpolationMethod to allow
its serialization to be shared.
Not yet used by any font backends.
