VecGetArray function requires the accessed vector not
to be locked.

Improve error messages

Update for new signature of the getValueBounds().
Generalize to more types.
Deduplicate creation of the entries.

Uses new getValueBounds().
Handles more types of mesh properties.
Differentiate differentiate more error types.

Change argument to existing property vector. This avoids
double search.

Also change return type to std::optional.

Handle more property types.

Also call MeshInformation::writePropertyVectorInformation() for similar
code parts.

[T/GL] DuplicateGeometry; Small cleanup.

[ci] Added missing docker login to ctest results job.

 - avoid variable shadowing by adding scope
 - use std::rand()
 - remove implicit and explicit casts
 - rely on actual size of geometry object (polylines)

The test would fail sporadically (say in one out of 10000) runs.
Reasons are not clear. My best guess is that the number of actually
stored polylines differ from the number of generated polylines.

A failing testrun would look like this:

 /Users/gitlab/builds/TqLuBEs-/0/ogs/ogs/Tests/GeoLib/TestDuplicateGeometry.cpp:92: Failure
Expected equality of these values:
  n_plys
    Which is: 6
  new_plys->size()
    Which is: 5
[  FAILED  ] GeoLib.DuplicateGeometry (1 ms)

[App] Partmesh; Exclude integration point data.

Closes #3013

inside the partmesh tool. Keep them otherwise.

Metis converted input prepared with
partmesh -i cube_1x1x1_hex_8.vtu --ogs2metis
mpmetis -gtype=nodal cube_1x1x1_hex_8.mesh 2

For now exclude the partitioning of this mesh item type.

Extend and correct the benchmark description page.

 - Replace the ASCII values and add new time steps to analytical solution file.
 - Use same mesh as for the tests (now in x-direction, not in z).
 - Update ctest references.

For both Newton and Picard non-linear solvers.

New results, very well comparable to the picard version.

No changes to the results.

If component transport is not enabled in
the configuration, the variable is unused.
