DEV: Updated weak Dir BC for Taylor-Hood elements

Weakly applied Dirichlet BC for fluids and FSI is now updated
for Taylor-Hood type discretization.

Some bugs related to function space allocation and second
derivative evaluation have been fixed.

1D and 2D elements were added for second derivative evaluation
including QUAD(1D), QUAD8 and QUAD9 elements.

TODO: some 3D elements still need to be included such as
HEX20, HEX27 and Wedge. A warning message is displayed now
that the second derivatives are not evaluated for these elements.
