Linux wants const char but Windoze wants const wchar_t in Ort::Session::Session

Describe the issue

I am compiling in both windows and linux onnxruntime version 1.14.1.

According to the documentation in here, the signature for the session ctor is:

Ort::Session::Session(Ort::Env&, const char*, Ort::SessionOptions)

In linux this seems to be so, but when compiling in windows, the compilation fails and the compiler complains about const char* and says that the ctor signature is this one instead:

Ort::Session::Session(const Ort::Env &,const wchar_t *,const Ort::SessionOptions &)

On the other hand, if I try to do that in linux, it fails (it wants const char*), so this is pretty bad inconsistency if one wants to write architecture-independent code: in linux it must be const char* and in windows const w_char*.

Start with the documented Ort::Session constructor and the implementation around line 937 of onnxruntime_cxx_inline.h. Reproduce the constructor call with the CMake/MSBuild Windows build and the Linux make build, then compare the platform-specific declarations and documentation. Done means the cross-platform constructor behavior and its documentation are consistent, with coverage for both targets.
