rustc_passes: Enforce `rustc::potential_query_instability` lint

Stop allowing `rustc::potential_query_instability` in all of `rustc_passes` and instead allow it on a case-by-case basis if it is safe. In this case, all instances of the lint are safe to allow.

Part of rust-lang/rust#84447 which is E-help-wanted.
