Intent to prototype and ship: hwb() colors

[Emilio Cobos Álvarez]

Summary: Enable hwb() color support (spec contains reasoning as for why
is it useful). The code was contributed by Adobe in:

https://github.com/servo/rust-cssparser/pull/292

Bug: https://bugzil.la/1352755

Standard: https://drafts.csswg.org/css-color-4/#the-hwb-notation

Platform coverage: All

Preference: None (it's a trivial extension to the already-shipping hsl()
code, so I think we probably don't need it).

DevTools bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1743107

Other browsers:

* WebKit/Safari supports this.
* Chromium doesn't.

web-platform-tests: There are quite a few and we pass them with the patch.

I want to point out that there is some difference to the existing hsl() function, though. Namely, hwb() only supports the newer space-separated syntax, not the old comma-separated syntax. See https://bugzilla.mozilla.org/show_bug.cgi?id=1747528 for further information.

Thanks, that's a really good catch!

FWIW, I'm not sure I agree with it, filed:

https://github.com/w3c/csswg-drafts/issues/6911

But for now I'll fix in:

https://github.com/servo/rust-cssparser/pull/295

And make sure we don't ship the comma syntax unless the above issue is
resolved in another direction.
