Rollup merge of #79061 - jyn514:no-pub, r=GuillaumeGomez

Make all rustdoc functions and structs crate-private

This gives warnings when code is no longer used, which will be helpful when https://github.com/rust-lang/rust/pull/77820 and https://github.com/rust-lang/rust/pull/78082 land.

AFAIK no one is using this API.
