Add GitHub workflow for continuous integration for Windows

[IAmNotHanni]

Related to #467

We can already use GitHub actions for continuous integration (CI) for the Windows build.
This workflow builds the code using MSVC compiler and clang for Windows, each in both debug and release configuration.
The results are uploaded as artifacts in a nightly build.

Let me know if you request changes to the workflow.

best regards

Just one comment, otherwise looks good to me.

I noticed that a downloadable artifact is a ZIP archive with another ZIP archive inside. Can we avoid this double-packing?

I am not sure if we need any artifacts to download later. This is a library distributed in the source form. All we need from the automated builds is the log with errors and warnings.

I can see you are downloading LLVM from repository https://github.com/zufuliu/llvm-utils. It doesn't look like an official LLVM account. Is there no official distribution of those binaries?

Oh, true. I will remove this and see if it still compiles (if clang is installed by default in visual studio in the workflow).
If not, I will just remove clang for Windows for now. It's not that important I think, and we still have clang for Linux.

It seems that Clang has failed.
