Summary: add support for nlu specific input
Test Plan:
tested
```
buck run aibench:run_bench -- -b aibench/specifications/models/pytorch/fbnet/assistant_mobile_inference.json --platform android/full_jit --framework pytorch --remote --devices SM-G950U-7.0-24
```
make sure it compatible with previous test
```
