…ensorSpecs (#18078) Stack from [ghstack](https://github.com/ezyang/ghstack) (oldest at bottom): * #18080 * #18328 * #18079 * __->__ #18078 Add end-to-end device type annotation support from export to runtime. Currently we only support one device per graph The overall pipeline is: a. Partitioner use `compile_spec` to determine which device the partitoned blob is runing on b. after lowered partitioned graph to backend, the new-introed propagate_device_pass will annotate the input and output tensors of delegate blob as target device.
