Set ANDROID_USE_LEGACY_TOOLCHAIN_FILE to false (#23544)
NDK has two toolchain cmake files as you can see in 

https://android.googlesource.com/platform/ndk/+/refs/heads/main/build/cmake

By default NDK use the legacy one for providing the best compatibility.
We don't need to. This PR changes to use the new one.

The new toolchain cmake file uses standard cmake flags like
CMAKE_ANDROID_RTTI to control C++ features.

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.

ONNX Runtime training can accelerate the model training time on multi-node NVIDIA GPUs for transformer models with a one-line addition for existing PyTorch training scripts. Learn more →
