[node] Fix logging mutex crash at exit on macOS

[fs-eire]

Description

This change fixes a bug that causes crash on macOS (and also potentially other platforms using libc) at OrtReleaseEnv.

Now we don't let the destructor of OrtEnv to be called if the program exits unexpectedly.

Motivation and Context

Fixes #24579

Pull Request Overview

This PR refactors the mutex protecting the default logger by converting it from a function-local static (Meyer's Singleton pattern) to a static class member. The mutex is moved from the DefaultLoggerMutex() function to LoggingManager::default_logger_mutex_.

• Removed the DefaultLoggerMutex() function and replaced it with a static member variable
• Updated all references to use default_logger_mutex_ instead of DefaultLoggerMutex()
• Updated the comment in CreateDefaultLogger() to reflect the new name

Updated the PR to use a totally different implementation. Now the latest change only modify nodejs binding to ensure no OrtReleaseEnv is called if onnxruntime DLL is closed.
