Initial buildbot image for Windows with Visual Studio 2019

[kuhnel]

Summary

First shot at a docker image for building on Windows. It's a mixture of the image we're using for pre-merge testing and the buildbot-mlir-nvidia image. It's not yet tested.

The current state of the buildbot is on http://lab.llvm.org:8014/builders/clang-x86-ninja-win10

I'd use \volume\<docker-volume-name>.
Volumes are fairly common source of surprises. Making it obvious that some path involves external magic removes one source of surprises. Making name consistent with external configuration saves time on figuring out where particular bits really come from.

Nit: I'd wrap the long lines to make it more readable as plain text.

Sorry to nit but this file and a couple others are missing a newline at EOF.
