Qualcomm AI Engine Direct - Runtime Option

[winskuo-quic]

Summary

Supporting following options that can be set during both AOT and runtime:

• Log Level
• Performance Mode
• Profiling Level

Test plan

• Log Level: Check debug message prefix exists.
• Performance Mode: Ensure QNN SDK prints config log for performance, and ensure burst is faster than high power saver.
• Profiling Level: Turn profiling off in compile spec and add profiling flag in runtime, ensure profiler gets expected number of events.

Is it needed to have these headers?

#include <executorch/backends/qualcomm/runtime/QnnBackendOptions.h>
#include <executorch/backends/qualcomm/runtime/QnnExecuTorchBackend.h>

[cccclai]

And these two

#include <executorch/runtime/backend/backend_option_context.h>
#include <executorch/runtime/backend/interface.h>

Thanks for reviewing the PR and catching this.
Some of these headers are not required and I have removed them.
However, QnnExecuTorchBackend.h would still be required since the backend name variable QNN_BACKEND is inside QnnExecuTorchBackend.h. If there are any concerns, I can move this variable to somewhere else.
Thanks
