  Revert "[clang] Fix missing diagnostic of declaration use when accessing TypeDecls through typename access (#129681)"

This caused incorrect -Wunguarded-availability warnings. See comment on
the pull request.

> We were missing a call to DiagnoseUseOfDecl when performing typename
> access.
>
> This refactors the code so that TypeDecl lookups funnel through a helper
> which performs all the necessary checks, removing some related
> duplication on the way.
>
> Fixes #58547

> Differential Revision: https://reviews.llvm.org/D136533
