Use new changes from cssparser and use the new lab/lch/oklab/oklch color formats. Introduced a new color type AbsoluteColor. It represents any kind of color that has absolute numerical values. It is also tied to a color space and therefore can be trivially converted to another color space. Differential Revision: https://phabricator.services.mozilla.com/D163579
