a34b1107 - [flang] Check for BIND(C) name conflicts with alternate entries (#156563)

[flang] Check for BIND(C) name conflicts with alternate entries (#156563) Added IsAlternateEntry() and modified IsExternalProcedureDefinition() to also check for alternate entries. (IsExternalProcedureDefinition() is called from CheckHelper::CheckGlobalName(), which checks for duplicate global symbols.) Fixes #62778
