Qualcomm AI Engine Direct - GA Model Enablement (deit) (pytorch#11065)

On behalf of @chenweng-quic

### Summary
- support e2e script / test case for GA deit model
- perf: 8a8w 2.7ms/inf (SM8750)
- acc: top1/5 ~= 80%/90%

### Test plan
```bash
python backends/qualcomm/tests/test_qnn_delegate.py -k TestExampleOssScript.test_deit --device <device_id> --host <host> --model <soc_model> --build_folder build-android --executorch_root . --image_dataset imagenet-mini/val --artifact deit_artifact
```
