Merge branch 'iulian787/data_ocean_model' (PR E3SM-Project#6249)

Add support for the MOAB coupler in data-ocean.

This allows running F-cases that have ocean as the only data model and use MPAS-Seaice with the moab coupler.

On the component data side, instance a new imoab application whose degrees of freedom are aligned with the regular
domain decomposition from the data model. More changes were needed on the coupler side, because previous coupled cases did not have samegrid_ao flag true.
Also, changes in the intel compiler or bios on chrysalis uncovered other needs about initialization of
mpi_reduce variables. (mpi_reduce is needed for comparisons between mct and moab fields,
in debug/verification mode)

Also add MOAB libs to perlmutter.
