Re: [csswg-drafts] [css-anchor-position-1] Allow anchor references to match names in outer tree scopes (#9408)

Okay, as part of solving #7916 (and slightly reworking how we described #5984), this is now properly defined across Scoping and Anchor Position. Anchor references (`position-anchor`, `anchor()`, etc) have well-defined tree-crossing behavior, and can match names defined in ancestor trees.

(They still can't match names defined in lower shadows; that'll need to be a separate feature that "lifts" a name out. Need to coordinate what that'll look like across a couple of similar properties.)
