Support having a different forward method when we are not in scripting mode (#38158)
Summary:
TorchScript currently doesn’t support `*args, **kwargs` in method signature, which is extensively used in DPER3 low-level modules’ forward method. In order to make DPER3 low-level modules scriptable, I was thinking about a solution of having a forward method *only* for TorchScript, and replace the forward method when we are not in scripting mode.
This solution works today, and I would like to add a test to make sure it will always work in the future.
