  [css-color] Clamp lab/lch/oklab/oklch components to appropriate ranges
https://bugs.webkit.org/show_bug.cgi?id=261019
rdar://114808444

Reviewed by Antti Koivisto.

According to the spec:
- Lightness for lab/lch should be clamped to a max of 100% (percentage) or 100 (number)
https://drafts.csswg.org/css-color/#specifying-lab-lch
- Lightness for oklab/oklch should be clamped to a max of 100% (percentage) or 1 (number)
https://drafts.csswg.org/css-color/#specifying-oklab-oklch

Apply that maximum and also fix some relative color syntax tests that weren't expecting the clamping.
