Re: [csswg-drafts] [css-color-4] Allow out-of-gamut HSL/HWB colors (previously "Move gamut mapping to a future spec") (#8444)

> It is however a breaking change from currently shipping implementations in WebKit, Chromium and Gecko and would require changes to existing WPT tests including tests which were tagged Interop2022 so I am requesting further discussion from implementers, and Agenda+ to get a resolution.

Relative color is not yet shipped anywhere and no RCS tests were part of Interop2022.

`color-mix` is shipped in Safari and Chrome, but the [gamut-mapping](https://github.com/web-platform-tests/wpt/blob/master/css/css-color/parsing/gamut-mapping.html) tests were also not part of [Interop2022](https://wpt.fyi/results/css/css-color/parsing?label=master&label=experimental&product=chrome&product=firefox&product=safari&aligned&view=interop&q=label%3Ainterop-2022-color).

There were some tests that were a part of Interop2022 that would need to change. All `color-mix` tests here that used `hsl` or `hwb` as a colorspace, but AFAICT that is all:
