[flang] Catch error: COMMON block and implicit interface external subprogram with same name

Declaration checking catches the error of a COMMON block and a subprogram
definition having the same name, but misses the case of a COMMON block
and an a reference to an external subprogram with an implicit interface.
Fix.  Fixes bug https://github.com/llvm/llvm-project/issues/63247.
