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

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
