QNN EP Sample - Fresh build with latest official QNN package produces errors on ARM64 Snapdragon QC PC

[ivberg]

I used official latest ORT 1.20 pre-built package per https://onnxruntime.ai/docs/execution-providers/QNN-ExecutionProvider.html#pre-built-packages-windows-only

It looks to use QNN_2.27.0.240926142112_100894

After build and execute, some of the executions will produce error messages or crash
