This PR adds specific check-cfg diagnostics for unexpected cfg in external macros.

As well as hiding the some of the Cargo specific help/suggestions as they distraction for external macros and are generally not the right solution.

Follow-up to #132577

Question: is this still problematic?

Answer: yes, crate_name is on tcx, early ctxt doesn't have access to a cstore

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.
