### Description This is exposing the already existent interface of asynchronous work of all CUDA base EP's (CUDA + TensorRT). ### Motivation and Context This is something requested in #12216. It will enable users to build an efficient data pipeline with ONNXRuntime and CUDA pre-/post-processing. PCI traffic to the CUDA device can be run during inference as soon as the postprocessing consumed the input buffer and it can be overwritten. To do this work has to be submitted async to the device. Please see below screenshots showing the illustration of this using NSight Systems. Async: <img width="1401" alt="image" src="https://user-images.githubusercontent.com/44298237/209894303-706460ed-cbdb-4be2-a2e4-0c111ec875dd.png"> Synchronous: <img width="1302" alt="image" src="https://user-images.githubusercontent.com/44298237/209894630-1ce40925-bbd5-470d-b888-46553ab75fb9.png"> Note the gap in between the 2 inference runs due to issuing PCI traffic in between and to the CPU overhead the active synchronization has. --------- Co-authored-by: Chi Lo <chi.lo@microsoft.com> |

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.
