[csswg-drafts] [css-color-5] Any identifier should be valid at parse time for RCS in `color()` (#8412)

LeaVerou has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-color-5] Any identifier should be valid at parse time for RCS in `color()` ==
https://drafts.csswg.org/css-color-5/#relative-color-function

css-color-5 allows us to describe components of custom color spaces via the [`components`](https://drafts.csswg.org/css-color-5/#descdef-color-profile-components) descriptor. However, we cannot have syntax that becomes invalid at parse time based on the value of a descriptor.
Therefore, we should allow *any* identifier to be used for RCS in `color()` at parse time, and make it IACVT if the wrong identifiers are used.
