net/openmpi: switch to hwloc2

Many scientific ports depend on MPICH, and they are often installed on workstations where OpenMPI is also installed, e.g. because they depend on VTK (some math/vtk_).

Thus, if we upgrade net/mpich to 3.4, for which devel/hwloc2 is required (See PR 252494), it would be fine to make openmpi also depend on hwloc2 to avoid conflicts.

  net/openmpi3: Use the embedded hwloc library to workaround a conflict between hwloc and hwloc2 due sysutils/slurm-wlm.

  OpenMPI3 is not compatible with hwloc2. Also, OpenMPI3 was deprecated by upstream and will be removed from the ports tree as soon as all the ports which depend on it are moved to net/openmpi.
