Make use of Windows Shared Runners in GitLab
As seen here: https://gitlab.com/psi29a/openmw/-/jobs/525045358
Code in question: https://gitlab.com/OpenMW/openmw/-/blob/master/.gitlab-ci.yml#L44-66
We finally have access to windows shared runners, but it is a bare-bones win10 instance. We need to work out how to bridge this to make use of our CI scripts.
What's currently in the repo, commented out, is a custom runner with msys2 installed and MSVC2017 (including bash).
Hopefully someone with more knowledge than windows than myself can help here and get it to the point that we can make use of any artefacts produced.
This will hopefully remove are dep on AppVeyor.
