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

This PR removes `#![allow(rustc::potential_query_instability)]` line from [`compiler/rustc_metadata/src/lib.rs`](https://github.com/rust-lang/rust/blob/master/compiler/rustc_metadata/src/lib.rs#L3) and converts `FxHash{Map,Set}` types into `FxIndex{Map,Set}` to suppress lint errors.

A somewhat tracking issue: https://github.com/rust-lang/rust/issues/84447
