Remove EOS template parameter from compositional fluid model

[dkachuma]

The purpose of this PR is to remove the equation of state template parameter from CompositonalFluidModel. The reason for this is to reduce the number of types listed in MultiFluidSelector.hpp. If too many types are listed here the CUDA builds fail to build CompositionalMultiphaseFVM::applyFaceDirichletBC (CompositionalMultiphaseFVM.cpp).

Removing the EOS template parameter from CompositonalFluidModel cuts the number of types from 4 to 2. Instead of the EOS being implicitly determined by the object type, there is a user field equationOfState (similar to CompositonalFluidModelPVTPackage) which determines the EOS to be used. The downside is that the EOS parameters have to be passed to the compute kernels. The selection is now done with if-else statements (e.g. FugacityCalculator.hpp).

Despite this, the build still fails when the LBC model is added. Follow up PR's to remove the viscosity template parameter as well.
