### Description 1. Remove the onnxruntime::OrtMutex class and replace it with ~absl::Mutex~ std::mutex. 2. After this change, most source files will not include <Windows.h> indirectly. ### Motivation and Context To reduce the number of deps we have, and address some Github issues that are related to build ONNX Runtime from source. In PR #3000 , I added a custom implementation of std::mutex . It was mainly because at that time std::mutex's default constructor was not trivial on Windows. If you had such a mutex as a global var, it could not be initialized at compile time. Then VC++ team fixed this issue. Therefore we don't need this custom implementation anymore. This PR also removes nsync. I ran several models tests on Linux. I didn't see any perf difference. This PR also reverts PR #21005 , which is no longer needed since conda has updated its msvc runtime DLL. This PR unblocks #22173 and resolves #22092 . We have a lot of open issues with nsync. This PR can resolve all of them. |

ONNX Runtime is a cross-platform inference and training machine-learning accelerator.
ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries such as scikit-learn, LightGBM, XGBoost, etc. ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.
