Second stage of workflow depends on the first, runs on Windows:

* Restore the artifacts from the first stage into the right paths, includes all the files needed to continue the build
* Setup WiX, and call build.bat
* Upload the MSI Artifact along with the binary files (this is what someone would actually want to download)
