[export] Fix issue with internal model (#111140)
Summary:
This was error was run into when running ExportPassBase on an exported model with lifted constant tensors:
```
File "/data/users/angelayi/pytorch/torch/_subclasses/fake_tensor.py", line 1444, in dispatch
len(kwargs) == 0 and len(args) == 1 and type(args[0]) is torch.Tensor
AssertionError: (FakeTensor(..., size=(s0,)),) {}
While executing %lift_fresh_copy_1 : [num_users=1] = call_function[target=torch.ops.aten.lift_fresh_copy.default](args = (%_lifted_tensor_constant99,), kwargs = {})
Original traceback:
File "" in forward
mean = torch.tensor([0.485, 0.456, 0.406]).reshape(3, 1, 1)
```
In ExportPassBase, we retrace using the fake tensors in the placeholder nodes, but when running into this lift_fresh_copy operators, it's unable to be called with the fake tensors.
