### Description This PR partially reverts changes introduced in https://github.com/microsoft/onnxruntime/pull/15643 We make two API return std::string always in UTF-8. We also move the entry points from OrtApiBase to OrtApi to make them versioned. ### Motivation and Context `GetVersionString` always returns x.y.z numbers that are not subject to internationalization. `GetBuildInfoString` can hold international chars, but UTF-8 should be fine to contain those. We prefix them with u8"" in case the compiler default charset is not UTF-8. Furthermore, creating platform dependent APIs is discouraged. `ORTCHAR_T` is platform dependent and was created for paths only. On non-unix platforms would still produce `std::string` that can only contain UTF-8 The API was introduced after the latest release, and can still be adjusted. |

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.
