Expose a generic shape info struct for ONNXIFI Python interface (#42421)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/42421
Previously, we can only feed shape info from Python with float dtype, and batch based dim type when we do onnxifi from Python. This diff removes this limitation and uses TensorBoundShapes protobuf as a generic shape info struct. This will make the onnxifi interface in Python more flexible.
