[SMApp] Reimplementing the thick shell element of 4 nodes

[AlejandroCornejo]

📝 Description

This PR adds a new reimplementation of the old "ShellThickElement3D4N", now named:

• MITCThickShellElement3D4N and MITCThickShellCorotationalElement3D4N.

These new shells substitute the older ones -> @rickyaristio @rolandwuechner @RiccardoRossi @matekelemen so it WILL break the old cases. These new shells are fully compatible with all the constitutive laws present in the ConstitutiveLawsApp.

In order to update the cases:

For elasticity you may use the ReissnerMindlinShellElasticConstitutiveLaw or the ThicknessIntegratedIsotropicConstitutiveLaw for nonlinear ones (e.g. damage, plasticity).

I have updated a few tests but I am working on it right now. Since a few changes/improvements have been done to the old shell, we may expect noticeable differences of the results. IMO all changes have been done to improve its performance, especially in the nonlinear cases with plasticity (the result was horrible before).

Beside the developments described above:

I have added a new composite stacking shell constitutive law for modelling laminate composites together with the new thick shells.

These can be used by:

@RiccardoRossi @rickyaristio @singerTUM I have finished the implementation and validation of the 4 noded MITC thick shell and the laminate composite CL for shells. An old test of the shell has been updated and another one has been added to test the composite thickness integration CL.
