CI: Windows + CUDA

[ax3l]

Summary

This a CI entry for Windows MSVC + CUDA.

@robertmaynard @WeiqunZhang @mic84

Additional background

The install of CUDA takes about 10min, but we cache its install after the first run (this cache will be evicted after 7 days of inactivity).

Checklist

The proposed changes:

• fix a bug or incorrect behavior in AMReX
• add new capabilities to AMReX
• changes answers in the test suite to more than roundoff level
• are likely to significantly affect the results of downstream AMReX users
• are described in the proposed changes to the AMReX documentation, if appropriate

@robertmaynard not sure if relevant to your tasks, but we enabled .dll support in #1847 .

With this CI build (Windows + CUDA), I am still puzzled.

@ax3l May be add a cron option to on: to compile the Windows+CUDA build on a weekly basis?

I think you want the Ninja generator correct? But the CI config doesn't have an explicit Generator specified so you are getting Visual Studio ( I think that is the problem ).

I tried cmd terminal and -G Ninja in an earlier commit (2nd last), but that did not work either.

I am caching the download, but if it gets to build at some point and if it still runs a long time, then we should definitely do that.
