Computes the orbital-dependent part of the mGGA potential.

This reads as \( L\psi =-\nabla \cdot [\vtau \nabla \psi]\).

It is trivial to show that this operator is self-adjoint. However, this is never the case with finite differences. This is thus reimplemented as L\psi = -1/2(v_\tau \Delta \psi - \psi \Delta[v_\tau] + \Delta [v_\tau \psi]
