Failed to load image extension - Windows CUDA 11.7

🐛 Describe the bug

I observe following failures
https://github.com/pytorch/builder/actions/runs/4104686412/attempts/3
Windows CUDA 11.7, python 3.8-3.10

RuntimeError: Module torchvision FAIL: 1 Output: C:\Jenkins\Miniconda3\envs\conda-env-4104686412\lib\site-packages\torchvision\io\image.py:13: UserWarning: Failed to load image Python extension: 'Could not find module 'C:\Jenkins\Miniconda3\envs\conda-env-4104686412\Lib\site-packages\torchvision\image.pyd' (or one of its dependencies). Try using the full path with constructor syntax.'If you don't plan on using image functionality from `torchvision.io`, you can ignore this warning. Otherwise, there might be something wrong with your environment. Did you have `libjpeg` or `libpng` installed before building `torchvision` from source?

The above exception was the direct cause of the following exception:

Its same failure as: https://github.com/pytorch/vision/issues/7036
But now on windows.

Versions

nightly

Start with pytorch/builder/vision/test/smoke_test.py and the linked Windows CUDA 11.7 workflow run. Compare the failure with torchvision issue 7036 and investigate why image.pyd or its dependencies cannot load. Done means the Windows CUDA 11.7 smoke test passes and the image::decode_png and torchvision::roi_align operators are available.
