fvModels::filmToVoFTransfer,VoFtoFilmTransfer: New collaborating fvModels to transfer phase between VoF and film

These two new fvModels operate between a film and a VoF region to transfer film
to the corresponding VoF phase when the film is thick enough to be resolved by
the VoF solver or from the VoF phase to the film when the near-wall resolution
is too low and it is better to treat it as a wall film.

This functionality is equivalent to the VoFPatchTransfer fvModel developed for
the old film implementation but coded in a much more general manner with
implicit treatment of the mass loss from the film or VoF region for better
numerical stability and robustness.

The simple tutorials/modules/CHT/VoFToFilm case is provided to demonstrate a
film being deposited on a surface as the plate is withdrawn from a liquid.  It
is an updated version of the tutorials/modules/compressibleVoF/plateFilm case.
