Summary: trying to call `record_stream` on a tensor that is allocated on the CPU will result in error: ``` NotImplementedError: Could not run 'aten::record_stream' with arguments from the 'CPU' backend. ``` Change logic such that we only record GPU and MTIA backend tensors on streams, as there is no concept of a "stream" on CPU.
