bors 68511b574f Auto merge of #86676 - cjgillot:localexpn, r=petrochenkov 
Make expansions stable for incr. comp.

This PR aims to make expansions stable for incr. comp. by using the same architecture as definitions:
- the interned identifier `ExpnId` contains a `CrateNum` and a crate-local id;
- bidirectional maps `ExpnHash <-> ExpnId` are setup;
- incr. comp. on-disk cache saves and reconstructs expansions using their `ExpnHash`.

I tried to use as many `LocalExpnId` as I could in the resolver code, but I may have missed a few opportunities.

All this will allow to use an `ExpnId` as a query key, and to force this query without recomputing caller queries. For instance, this will be used to implement #85999.

r? `@petrochenkov`
