### Allow defining customized PythonOp shape inferer For `torch.autograd.Function`, we converted it to PythonOp in MSDomain, there are two places to do shape inferencing for it: 1. in SymbolicShapeInfer, there is one. 2. in PythonOp op definition. For common PythonOp, since we don't know the relation ship between inputs and outputs, so we only infer the rank from output ranks, and generate symbolic dimensions for each dim. While this will introduce many meaningless symbolic dimensions, sometimes blocking our graph transformers to do op fusion. This PR provide a way to define custom shape inferencing for `torch.autograd.Function` we defined, to propagate the original dimensions across the PythonOp at the best efforts. But the 2rd one is not covered yet, we could refine that later. Fixing 1st one is enough for ORTModule training/evaluation. ### Motivation and Context <!-- - Why is this change required?

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.
