[csswg-drafts] [css-color][css-color-adjust] We should add sufficient system colors to fully implement the HTML UA stylesheet (#4924)

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

== [css-color][css-color-adjust] We should add sufficient system colors to fully implement the HTML UA stylesheet ==
See <https://github.com/whatwg/html/issues/5426> for some more context. In that thread, @tomayac pointed out that link colors, because they're explictly defined to be `blue` and `purple` in the UA stylesheet, aren't being inverted when the UA is in a dark color scheme, making them very hard to read.

Obviously, [we have `linktext` and `visitedtext` system colors](https://drafts.csswg.org/css-color-4/#css-system-colors), so that particular issue should just be a matter of switching the UA stylesheet to using the system colors rather than explicitly naming them.

However, further discussion suggests that there are some colors in the UA stylesheet that aren't adequately addressed by system colors yet. If the UA stylesheet for plain HTML can't be done with system colors, we're probably missing some useful semantics, so we should make sure that the HTML stylesheet can be done purely in system colors.
