Rollup merge of #70119 - eddyb:typeck-tables-local-def-id, r=petrochenkov

Browse Source 
rustc: use LocalDefId instead of DefId in TypeckTables.

The logic in `TypeckTables`' implementation of `HashStable`, which created `DefId`s by combining a `CrateNum` from a `DefId` and a `DefIndex` from a `LocalDefId`, bothered me a bit.

I don't know how much this matters, but it works so might as well submit it.
