Re: [csswg-drafts] [css-conditional-5] Add ability to test for at-rule preludes (#6966)

This is relevant for browsers that want to ship style container queries, along with a feature query for testing support. I left more details in https://github.com/w3c/csswg-drafts/issues/6175#issuecomment-1232179302, but I think thread this is actually the proper place to make progress on the issue.

Would it be ready to bring back as a proposal with agenda+, or is there more discussion that needs to happen here? @tabatkins summary above looks reasonable to me, and better than one-offs like the `@supports container()` syntax that we approved in the other thread.
