We reuse the grid creation facility of the facet coupling framework and
require grid files that have the information on the fracture facets in
them. This enables us to reuse the codimension one grid adapter of the
facet coupling framework to identify which matrix element facets
coincide with a fracture.

This commit also introduces a test on the same geometry as in the 2.12
release.

TODO: add test for quads and tetrahedra

[test][seq] Remove superfluous semicolons in input file for test_diffusion3d

Fix clang compiler errors

Closes #550

See merge request !1188

* always return molecular diffusive flux, as name suggests

[test] add CMake guards for tests using UMFPack

See merge request !1199

[test][1p][sequential] use parameters instead of properties

See merge request !1198

The properties don't exist anymore. This has gone unnoticed since
SuperLU is available on all test platforms.

* fixes clang compiler error

* fixes clang compiler error

* resize local objects
* fixes clang error

* fixes clang compiler error

* fixes clang compiler error

* clang won't compile otherwise

* use Dune::Hybrid::elementAt() instead of std::get<>()

* due to a bug in clang (https://stackoverflow.com/a/47849501),
  myMultiTypeBlockvector.size() (which is static constexpr) has to be
  changed to MultiTypeBlockVector::size() to be used as a constexpr
  template argument
* probably a similar issue with using Dune::Hybrid::forEach and std::get<>
