Both plane strain and 3D, totally analogous to recent refactoring in #586 for CompressibleHyperelasticity. Includes exact solution tests for both 2D and 3D.
This is an unstabilized formulation, which is exactly Stokes in the linear case, so requires Q2/Q1 or analogous FEM spaces, so is quite a bit more expensive. Would be nice to add a stabilized formulation in the future.
Nearly incompressible requires just one small change in the pressure term.
