... from assembleWithJacobian() into a separate method.
I added some constitutive data structs and reused some from TRM.

Generic cell-average output

See merge request ogs/ogs!4984

Note: No reference data has been added, but existing data has been
renamed and used.

With that change, Process.h does not include the reflection code
transitively anymore, meaning less code dependencies and (hopefully)
better/more fine-grained incremental builds, since many other
compilation units depend on Process.h.

Warning was:

Could not get it to work. Fails when calling GMSH2OGS binary. Has almost
the same structure as notebook-inclined_bhe_meshing.md which runs fine.
