Reduce the number of phaseSystems libraries:

- phaseSystems previously had a number of smaller libraries to provide
  interface and model properties, etc. This potential flexibility was
  never actually used anywhere, but causes cyclic dependencies between
  phaseSystem and the models (and turbulence) that causes extreme
  difficulty for mingw linking (issue #1238).
