Robert Webb 7c9be45a48 [Turbopack] Include CSS URL attributes, including Layer, Media and Supports (#89300) ...

Note that this is my first contribution in Rust, so let me know if I
missed anything idiomatic or if there is a particularly better way to do
something.

Also, I did not use AI to create this at all, although I did chat a bit
to try to wrap my head around types.
