Handle `rustc_interface` cases of `rustc::potential_query_instability` lint

This PR removes `#![allow(rustc::potential_query_instability)]` occurrences from [`compiler/rustc_interface/`](https://github.com/rust-lang/rust/blob/master/compiler/rustc_interface/) <s>and converts `FxHash{Map,Set}` types into `FxIndex{Map,Set}` to suppress lint errors</s> (was not necessary for this PR).

A somewhat tracking issue: rust-lang#84447
