[md][ff-pm] Add freeflow porous medium coupling managers and test
Part of merging !2201 (closed) in smaller parts.
Improvement in comparison to old convergence test:
- Add stress tensor for analytical solutions
- add tests for dirichlet, neumann and mixed dirichlet-neumann boundaries in both domains
- test all implemented analytical solutions
TODO
-
Coupling manager: Make interface smaller (private) whereever possible -
Fix updateCouplingContext
