Allow extra unused arguments in symbolic shape function (#65095)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/65095
The reason I didn't do this initially was because I was worried that matching one schema to another schema with an extra argument might change semantics, e.g. Add(Tensor, Tensor) to Add(Tensor, Tensor, Tensor) might be different. However we don't actually need to worry about this because the graph schema isn't used for node matching, unlike symbolic_script.cpp
