[jit][edge] Print correct type strings in code file for mobile models. (#71968)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/71968
Right now when we output type to python files under `code/`, we directly write the dynamic type representation `Dynamic<>`, which causes server side to load an unsupported type. Instead we should do the fallback in export_module.cpp.
