Log filesystem path instead of string for C++20 compliance

[JanSellner]

Description

Log the std::filesystem::path object instead of the ORTCHAR_T string to avoid C++20 compliance issues.

Motivation and Context

ORTCHAR_T is a wchar_t on Windows and it is not allowed to pass that to std::basic_ostream.

Example

(example.cpp)

#include <iostream>
#include <filesystem>

int main() {
    const wchar_t* s = L"my/path";
    std::filesystem::path path(s);

    std::cout << s << std::endl;

    return 0;
}

Output on latest MSVC with /std:c++20:

<source>(8): error C2280: 'std::basic_ostream<char,std::char_traits<char>> &std::operator <<<std::char_traits<char>>(std::basic_ostream<char,std::char_traits<char>> &,const wchar_t *)': attempting to reference a deleted function
Z:\compilers\msvc\14.44.35207-14.44.35219.0\include\__msvc_ostream.hpp(972): note: see declaration of 'std::operator <<'
<source>(8): error C2088: built-in operator '<<' cannot be applied to an operand of type 'std::ostream'

Pull request overview

This PR fixes a C++20 compliance issue in the LoadPluginOrProviderBridge function where a wchar_t* string (represented as ORTCHAR_T* on Windows) was being logged to std::ostream, which is not allowed in C++20. The fix changes the logging statement to use the std::filesystem::path object instead.

Changes:

• Updated logging statement to use resolved_library_path (std::filesystem::path) instead of library_path (ORTCHAR_T*) for C++20 compliance

Can you rebase your branch to pickup the latest main? We're not able to trigger the CIs which are required before checkin and that might be the cause as the problem only seems to affect your PR.
