Unrolled build for rust-lang#134339

Rollup merge of rust-lang#134339 - Urgau:tcx-in-early-diag, r=jieyouxu

Pass `TyCtxt` to early diagostics decoration

This PR pass a `TyCtxt` to the early diagnostics decoration code so that diagnostics code that take advantage of (a very limited but still useful) `TyCtxt` in their note, help, suggestions, ...

This is particulary useful for rust-lang#133221 which wants to get the crate name of a `DefId`, which is possible with `tcx.crate_name(...)`.

I highly recommend reviewing this PR commit by commit.
