Issue to fix:
The static OnnxLoader::loader object may be destroyed by the system before the customer's cleanup code (e.g., TRITONSERVER_ServerDelete) runs.
This premature destruction causes an assertion failure inside ONNX Runtime initially. Even if the assertion is suppressed, it leads to double-free errors detected by the system during shutdown.
Proposed solution:
Modify the OnnxLoader destructor to explicitly set the internal pointer to nullptr.
This ensures that subsequent null checks on loader in UnloadSession and Stop methods function correctly, preventing use-after-free or double-free issues.
