Explore using a dev drive for windows CI

[konstin]

We observe that windows is much slower on any io operations, e.g. just downloading and unpacking the python versions takes 1.5min. We should explore using using a VHDX virtual harddisk as described in actions/cache#752 (comment) to see if this solves the performance bottleneck in github actions.

FYI there are some details here where this was reccomended for pip to do: pypa/pip#12055

Ultimately pip maintainers are very conservative about adding new features, but you might find the post informative.
