To form a material intrinsic permeability tensor, some elements duplicate the coding also found in GeoElementUtilities::FillPermeabilityMatrix. Further the user input checking of Youngs modulus and Poisson's ratio is part of the constitutive law checks, but also done in elements. Checking of directional permeability user input is also duplicated.

This issue aims at removing the duplications and reusing the functionality across the elements.
