Hi,

I would love to start using the Windows Runners.
So, really happy to see PR #1525 by @maths22!

My toolchain requires Visual C++ (VS2019) on top of this Windows-Core-2019 image.
As far as I know, for Windows it is not so easy to use a bare agent and install dependencies for each build. (or has this improved?)
So, I would like to build an image based on Windows-Core-2019 and add VS2019 build tools & Windows SDKs via chocolatey packages.

Happy to bring this in a PR., but looking for some advise before I start:

• shall I add another image to enable this? (e.g. windows-core-2019-vs2019) Or does this specific image belong in a separate repo?
• Are there already ideas on how to support a variety of images? (e.g. ephemeral runners, scaling out from 0 when needed)

Perhaps @ScottGuymer or @npalm will know the answer :)

Thanks!
