ENT-10801: Moved sftp cache Wix Tools install from jenkins-vms to package-msi script

[craigcomstock]

Might as well move the knowledge as close to where it is needed to avoid trouble.

I'm not sure about this. Installation of tools required for the build has traditionally been done in the build machine setup.

Sure. But I would prefer that the knowledge of how to setup a build machine is close to where a build machine is used: here.

Ideally I'd like to see all the distribution package dependencies moved here as well.

e.g. https://github.com/cfengine/buildscripts/blob/master/ci/setup.sh and https://github.com/cfengine/buildscripts/blob/master/ci/setup-projects.sh made more generic so they work on all supported platforms.

As discussed on Slack this should be a temporary fix until we move mingw builds into containers which should then have all the necessary bits in the container image(s).
