Remove LocalDefId <-> HirId global maps

[cjgillot]

Based on #89124.

The LocalDefId <-> HirId maps were globally accessed through tcx.definitions. They are now encoded using the HIR queries.

• For HirId -> LocalDefId, a side map is added inside hir_owner_nodes(hir_id.owner), indexed by hir_id.local_id.
• For LocalDefId -> HirId, the mapping is obvious if the local_def_id is an HIR owner, ie. if hir_owner is Some. Therefore, we use the None case to store the non-owning HirId.

There is a special case with use trees, which can have a LocalDefId, which should be an HIR owner, but with no associated HIR data structure. In that case, we store the information like non-owning definitions.

Summary: This change led to very large relevant regressions 😿 in compiler performance.

• Very large regression in instruction counts (up to 9.0% on incr-unchanged builds of match-stress-enum)

If you disagree with this performance assessment, please file an issue in rust-lang/rustc-perf.

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR led to changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please fix the regressions and do another perf run. If the next run shows neutral or positive results, the label will be automatically removed.
