PETSc CMake fix and updated juwels modules

PETSc CPM

There is no PETSc module availabe (yet), CPM

• request to juwels support: --> PETSc now in work 3.18.5

CMAKE_BUILD_PARALLEL_LEVEL

CMake then may spawn as many processes as available, but this will overload the filesystem on JUWELS.

• It is therefore necessary to limit the number of processes with CMAKE_BUILD_PARALLEL_LEVEL export CMAKE_BUILD_PARALLEL_LEVEL=6 is added

VTK CPM

• VTK (9.2.5) is not compatible with the MPI version of HDF5 (1.12.2)
• VTK has its own implementation of a (serial!) HDF Reader and Writer
• do not 'module load VTK/9.2.5' build VTK via CPM

OpenMPI instead of ParaStationMPI (temporary workaround)

LAPACK can not be loaded with ParaStationMPI

• request to juwels support (wip)
