lagrangian: Moved composition modelling into the thermo cloud

The thermo parcel now supports thermophysical property modelling. This
particle does not store phase or specie fractions so it only provides a
single phase with a uniform composition. Additional specification is
required in the cloud subModel configuration in order to select the
specie. For example:

    compositionModel singlePhaseMixture;

    singlePhaseMixtureCoeffs
    {
        phases
        (
            solid
            {
                CaCO3   1;
            }
        );
    }
