cb263919 - [flang] Make proc characterization error conditional for generics (#89429)

[flang] Make proc characterization error conditional for generics (#89429) When the characteristics of a procedure depend on a procedure that hasn't yet been defined, the compiler currently emits an unconditional error message. This includes the case of a procedure whose characteristics depend, perhaps indirectly, on itself. However, in the case where the characteristics of a procedure are needed to resolve a generic, we should not emit an error for a hitherto undefined procedure -- either the call will resolve to another specific procedure, in which case the error is spurious, or it won't, and then an error will issue anyway. Fixes https://github.com/llvm/llvm-project/issues/88677.
