Rollup merge of #120339 - petrochenkov:nameprivisit, r=michaelwoerister

privacy: Refactor top-level visiting in `NamePrivacyVisitor`

Full hierarchical visiting (`nested_filter::All`) is not necessary, visiting all item-likes in isolation is enough.
Tracking current item is not necessary, passing any `HirId` with the same parent module to `adjust_ident_and_get_scope` is enough.

Follow up to rust-lang/rust#120284.
