Changes:
* Build installer projects in parallel.
* Use `ProjectReference` to ferry bits between installer projects.
* Don't build wixproj to a unified output directory. This was only done to simplify finding file paths to MSI's built by other projects, but ProjectRef solves that.
* Add a VS solution for working on wixproj and the associated C++ custom actions.
* To make wixproj work in VS, I replaced default globs with listing .wxs and .wxl files in the wixproj file.
* Add a target to copy the installers to the artifacts directory according to the layout described in /docs/Artifacts.md
This code previously was in private repos because it had references to internal locations and drop shares. This code has been modified to remove these internal-only pieces.
