Use AppendExecutionProvider_Dnnl api to add onednn EP，No success

[yunhaolsh]

First i use commond '--use dnnl' to build a onnxruntime.dll enable oneDNN support.
When i use this code to register a dnnl EP to ORT：
int threadNum = 4;
bool enable_cpu_mem_arena = true;
OrtDnnlProviderOptions dnnl_option = { enable_cpu_mem_arena, static_cast<void*>(&threadNum)};
session_options.AppendExecutionProvider_Dnnl(dnnl_option);
session_options.SetIntraOpNumThreads(4);
session_options.EnableProfiling(L"det_Profiling");
session = Ort::Session(env, model_path.c_str(), session_options);
From det_Profiling.json i find threr always is "provider" : "CPUExecutionProvider"，
When i use
GetAvailableProviders()
I got "DnnlExecutionProvider" and "CPUExecutionProvider"
How can i use DnnlExecutionProvider as my EP？
Why my Profiling file always is "provider" : "CPUExecutionProvider"？
Is there something miss to config with ORT session? Thanks.
