Re: [csswg-drafts] [css-fonts-4] font-display says it's valid in @font-feature-values but it isn't an at-rule

It's allowed in @font-feature-values so you can apply a `font-display` even if you don't have control over the @font-face rules themselves - as mentioned, this is useful for the Google Fonts case.

The only actual requirement is that at-rules can't contain both style rules and declarations; since @font-feature-values doesn't contain either yet, it's fine to make it contain the font-display declaration. It just needs to be defined to do so.
