Can we try to reduce the hardcode version and refer to this https://github.com/pytorch/executorch/blob/main/backends/qualcomm/scripts/qnn_config.sh ? If it needs to refactor a bit that's fine

Ah yeah I just meant this part /tmp/qnn/2.28.0.241029, the 2.28.0.241029 can be different when we bump the qnn version
