What is the problem that this feature solves?

ONNX checker currently checks model proto validity with check_model_proto. I would be very helpful to have a similar API that checks for function proto validity.

This greatly helps testing function libraries built with ONNX script.

Alternatives considered

Make a model. Not all functions can be directly converted into a Model.
