Persist torch.assert in aten graph (#100101)
This PR introduces a new operator called aten._assert_async.msg, which allows passing a tensor value and assertion message as inputs. As part of TorchDynamo, we're replacing the use of torch._assert with this new operator so that make_fx also knows how to handle assertions. This is subset of https://github.com/pytorch/pytorch/pull/98878, refer there for historic reviews.
