* [Windows] Workaround for loading bundled DLLs

Python-3.8+ adds `add_dll_directory` call, see https://docs.python.org/3/whatsnew/3.8.html#ctypes
Simulate this behaviour on older versions of Python runtime by calling
`LoadLibraryExW` with the appropriate flags

Fixes https://github.com/pytorch/vision/issues/4787

This reverts commit 85b78580.
