  [Clang] Diagnose invalid function types in dependent contexts (#138731)

When forming an invalid function type, we were not diagnosing it if the
call was dependent.

However, we later rely on the function type to be sensible during
argument deduction.

We now diagnose anything that is not a potential function type, to avoid
constructing bogus call expressions.

Fixes #138657
Fixes #115725
Fixes #68852
