model_dump working with delegate models (#61043)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/61043
Trying to make model_dump work with delegate models
ghstack-source-id: 132809755
Test Plan:
N509022.
The data.pkl in the lowered model:
```
bash-3.2$ python -m torch.utils.show_pickle /Users/myuan/models/backend/lowered_model.pt@*/data.pkl
torch.jit.backend_with_compiler_demo.LoweredModule.__torch__.___torch_mangle_5.ModuleAdd()(state=
(torch.jit._pickle.restore_type_tag({'forward': torch.jit._pickle.restore_type_tag({'input_shapes': '((1, 1, 320, 240), (1, 3))',
'some_other_option': 'True'},
'Dict[str, str]')},
'Dict[str, Any]'),
torch.jit._pickle.restore_type_tag({'forward': 'prim::Constant#1<debug_handle>271,aten::add<debug_handle>272'},
'Dict[str, str]'),
True))
```
Comparing to data.pkl in scripted_model.pt:
```
__torch__.___torch_mangle_7.ModuleAdd()(state=
{'_is_full_backward_hook': None, 'training': True})
```
