Qualcomm AI Engine Direct - fix optrace demo script and remove redundant flags from QNN tool (#16487)

Qualcomm AI Engine Direct - Fix OpTrace Profiling demo script

### Summary
 - Fix OpTrace Profiling demo script
 - remove redundant flags from QNN tool
 
### Test plan
``` bash
python -m examples.qualcomm.util_scripts.qairt_visualizer_demo -s {SERIAL_NUM} -m ${SOC_MODEL} -b build-android -a ${path_to_output_folder}
```

``` bash
python -m examples.qualcomm.util_scripts.qairt_visualizer_demo -s {SERIAL_NUM} -m ${SOC_MODEL} -b build-android -a ${path_to_output_folder} --online_prepare
```

``` bash
python -m backends.qualcomm.tests.test_qnn_delegate.TestUtilsScript.test_debugger_generate_optrace  -s {SERIAL_NUM} -m ${SOC_MODEL} -b build-android --executorch_root . -a .
```
