solver3: Refactor Install(Ver) to PropagateInstall(Ver)

This is the first part of changing from Install() to Enqueue() for
installs, affecting only the versions. For packages, we still have
to resolve the group changing: When propagating cleanly, we don't
have the information as to which group the package was part of,
hence we are no longer able to queue the version selection of
upgrades before obsolete packages, for example, which needs
solving.
