### Description 2 models are added in CI. Stabe diffusion Model stage is based on https://github.com/microsoft/onnxruntime/blob/main/onnxruntime/python/tools/transformers/models/stable_diffusion/README.md LLama2 FP16 is based on https://github.com/microsoft/Llama-2-Onnx. 12G GPU memory is not enough, so I choose T4 to run it. ### Motivation and Context Add regular E2E test for big models. It will be triggered in main build, that is, it'll run after one PR is merged. More models will be added later. ### Test Runs ### https://dev.azure.com/onnxruntime/onnxruntime/_build/results?buildId=1275191&view=results
