22787aec - [QNN EP] Add platform-agnostic EP option to specify QNN backend, `backend_type` (#24235)

[QNN EP] Add platform-agnostic EP option to specify QNN backend, `backend_type` (#24235) Add a platform-agnostic EP option to specify QNN backend, `backend_type`. In typical usage, this should supersede the `backend_path` EP option. `backend_path` requires specifying a path to the QNN backend library which is different between Windows and non-Windows platforms (e.g., QnnCpu.dll vs. libQnnCpu.so). It will not be removed for backwards compatibility. It also provides the flexibility to specify an arbitrary backend path.
