[JIT] Add a pass for removing a first (self) argument from a graph if it is unused. (#57169)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/57169
The pass is planned to be used in AOT pipeline, where we expect input
graphs to be functional. As such, these graphs should not use 'self'
argument even if it is present, and thus it can be remove safely.
