[LD] F bar method for total Lagrangian formulation

This MR. brings the implementation of the F bar method for total Lagrangian formulation.

Note: this MR includes one of the commits of MR !4850.

TODO: issue with non-elastic models, or stress dependent models, where MFront does not know that the given stress has already been modified with F-bar (to be tested and verified with a simple example); algorithms for axi-symmetric problems; Jupyter Notebook benchmark.
