The accent-color computation right now chooses between black and white,
which is not ideal.

I tried to make it so that authors could choose the foreground colors in
the linked CSSWG issue from the comment, but that didn't go anywhere.

I think choosing a contrasting color that is in-line and contrasting
enough with the accent-color chosen by the page when darkening is better
than just black or white.

If we want the black-or-white behavior we can just change
layout.css.accent-color.target-contrast-ratio to something large enough.

https://accent-color.glitch.me/ is a nice playground to see this patch
in action.

Depends on D120722

No other property returns currentcolor in the computed style, and
Chrome agrees with us on this test.
