And then remove tcx.opt_hir_node(hir_id) in favor of tcx.hir_node(hir_id).

this is great!

perf run just to check 🤷, but i'll honestly probably approve this even if there is a minimal perf hit

Do we really need to store that span? Could we return DUMMY_SP when needed?

We could return DUMMY_SP, yes.
index_hir just has a close enough real span that can be used, so I used it (that makes Node::span always return real spans).

TODO: Also need to check whether these HirIds could be removed instead, maybe they are not really necessary and were added by mistake.

The HirId in Let turned out to be unnecessary, other HirIds from this PR are used in more substantial ways.
Blocked on #120428.

Create some minimal HIR for associated opaque types

`LocalDefId`s for opaque types in traits and impls are created after AST -> HIR lowering, so they don't have corresponding HIR and return their various properties through fed queries.

In this PR I also feed some core HIR-related queries for these `LocalDefId`s (which happen to be HIR owners).
As a result all `LocalDefId`s now have corresponding `HirId`s and HIR nodes, and "optional" methods like `opt_local_def_id_to_hir_id` and `opt_hir_node_by_def_id` can be removed.

Follow up to rust-lang#120206.
