Auto merge of #73365 - Manishearth:rustdoc-vis, r=GuillaumeGomez

Record visibility of reexports for all items, not just type items

This fixes https://github.com/rust-lang/rust/issues/73363

Unfortunately I can't add a test for this since this bug is obscured by the cross-crate bug, being fixed in https://github.com/rust-lang/rust/issues/73363 . Tests will be added later.
