"profiling_level": "detailed" is not working for multi models qnn npu

**Describe the bug**
A clear and concise description of what the bug is.

For a qnn recipe, there will be multiple models in genai_config.json. But if I enable `"profiling_level": "detailed"` and `"enable_profiling"`, the second `"profiling_level": "detailed"` will not work.

```
"context_ctx": {
"filename": "context_ctx.onnx",
"session_options": {
"provider_options": [
{
"qnn": {
"htp_performance_mode": "burst",
"htp_graph_finalization_optimization_mode": "3",
"soc_model": "60",
"profiling_level": "detailed",
"profiling_file_path": "qnn1.csv"
}
}
],
"enable_profiling": "op1"
},
"run_on_token_gen": false
},
"iterator_ctx": {
"filename": "iterator_ctx.onnx",
"session_options": {
"provider_options": [
{
"qnn": {
"htp_performance_mode": "burst",
"htp_graph_finalization_optimization_mode": "3",
"soc_model": "60",
"profiling_level": "detailed",
"profiling_file_path": "qnn2.csv"
}
}
],
"enable_profiling": "op2"
},
"run_on_prompt": false
},
```

After run, op1.json op2.json and qnn1.csv exist, but no qnn2.csv.
