Add assign argument to torch.Tensor.module_load (#121158)
Make `torch.__future__.get_swap_module_params_on_conversion() == True` account for `assign` argument to `nn.Module.load_state_dict`
Similar to when `torch.__future__.set_swap_module_params_on_conversion()` is `False`, `assign=True` means that we do not incur a `self.copy_(other)` and the properties of `other` will be preserved
