NumLib: Update setting of DirichletBCs in Newton

See merge request ogs/ogs!4912

[Minor fixing]  a not rendered equation  in the web document CreepBGRa

See merge request ogs/ogs!5036

Results are visually identical but not equal. Reason is the lesser
number of iterations with the new method and the missing sigma/damage
update in postTimeStep. Essentially the sigma/damage are from the
previous iteration.

The results are visually undistinguishable.
Stresses and loading curves are identical.

Otherwise "divergence is detected" in the first iteration
of the first time step.

Otherwise the non-linear solver is stuck.

Instead of setting the solution in the Dirichlet nodes, the solution is
enforced through the r.h.s. This usually saves one global iteration and
more importantly avoids big jumps in the first iteration for mechanics
processes.

The system solved by PETSc-SNES is different one and so far
the methods could be reused. With upcoming changes to the
Newton's version of applying Dirichlet-BCs this is not
going to work anymore.

Additional check for coordinate system and small refactorings.
