Add inverted-colors variant (#11693)

Add a variant for the
[`inverted-colors`](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/inverted-colors)
media query.

This has been supported in Safari for a while. I'm also implementing
support in Chrome atm.

I've decided to only add the inverted-colors: inverted variant because
the `none` state isn't really useful.
