Update libtorch interfaces of TorchVision to 0.9.0+

[zhiqwang]

TorchVision has updated the C++ interface in pytorch/vision#3146, so the codes in development \ tree:82d6afb only work with PyTorch 1.7.x and TorchVision 0.8.x. The use of libtorch with TorchVision 0.8.x and TorchVision 0.9.x is different, and TorchVision has refactored these C++ interfaces half a year ago, our plan is to update the libtorch interface to PyTorch 1.8.0+ and TorchVision 0.9.0+ in the next release (v0.4.1) for better maintainability.
