[FEM] use magnetization constraint for 2D
- uses the constraint for 2D magnetodynamics to perform e.g. Elmer's tutorial non. 15 - modify the Material manager to get rid of magnetization but keep the vectorial functionality because in future there will be support for e.g. birefringence materials etc.
