Process inputs and outputs in fx interpreter (#74242)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/74242
The inputs and outputs of the graph module might be different from the graph inputs and outputs if users are using custom codegen. In interpreter, it runs the graph instead of the generated forward function so it might not work if user provides the inputs to the graph module. To fill the gap, we call `process_inputs` and `process_outputs` inside interpreter.
