[Onnxifi] Blacklist ops in the partitions that are supposed to run on CPU (#34991)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/34991
The definition for the partition to be run on CPU is that it will contain an empty device_id list. We chose this over an op with no partitioning info because
1. Backward compatible with models that don't have partitioning info
2. Being explicit can flush out issues in earlier stage.
Test Plan:
```
LD_LIBRARY_PATH=third-party-buck/platform007/build/fb-nnpi/lib ./sigrid/predictor/tests/scripts/launch_ads_test_predictor.sh -g --nnpi --force_models=175742819_0 --sigrid_force_model_dir=$HOME/models/ --smc_server_port=7447 --glow-num-devices=1 --glow_interpreter_memory=$((256<<20)) --caffe2_fbgemm_fake_fp16_clamp --glow_global_fp16 --glow_clip_fp16 --glow_global_fused_scale_offset_fp16 --fbgemm_deserialize_to_original_format --caffe2_dump_input_of_type=Onnxifi --caffe2_logging_print_tensor --caffe2_predictor_use_memonger=no --onnxifi_debug_mode=true --caffe2_dump_input_with_recordio --caffe2_predictor_onnxifi_max_batch_size=32 --caffe2_predictor_onnxifi_max_seq_size=9600 --glow_onnxifi_backend=Interpreter --onnxifi_blacklist_ops=SparseLengthsSum,SparseLengthsWeightedSum --glow_dump_graph
```
Now it hits a new error.
