Rollup merge of #75452 - michaelwoerister:sp-cache-more-query-keys, r=lcnr
self-profile: Cache more query key strings when doing self-profiling. This PR adds optimized `SpecIntoSelfProfilingString` implementations for two common query key types (`LocalDefId` and `WithOptConstParam`). This makes raw self-profiling data on disk 8-9% smaller for my two test cases (`regex` and `cargo`). The on-disk format is not affected, so no tooling updates need to happen. I also tried adding an impl for `Ty<'tcx>` (which should reduce size quite a bit) but the compiler did not allow me to add a specialized impl parameterized with `'tcx`. I don't know if there is an actual problem with that or if the implementation of specialization just doesn't support it yet. cc @wesleywiser @Mark-Simulacrum
