ci: use a custom powershell script to run windows tests

There are a couple things going on here.

First, we need to avoid building egl/wayalnd/x11 crates on windows
as they can't be built.

Then we need to avoid running -sys tests as they don't succeed
currently. See [1]

Finally use a matrix:parallel job to tests multiple build
configurations.
