surfaceFilmModels: Superseded by the new isothermalFilm and film solver modules

The new general multi-region framework using the isothermalFilm and film solver
modules and executed with foamMultiRun is a much more flexible approach to the
inclusion of liquid films in simulations with the support for coupling to other
regions of various types e.g. gas flows, Lagrangian clouds, VoF, CHT etc.  This
has all been achieved with a significant reduction in the number of lines of
code and significant improvements in code structure, readability and
maintainability.
