CI: migrate osx-cxx-pkgs-opt to ARM

Add in Barry's configure pkgs in this job:
--download-amrex --download-cmake --download-ctetgen --download-exodusii --download-hdf5 --download-hypre --download-ks --download-metis --download-ml --download-mumps --download-netcdf --download-parmetis --download-pnetcdf --download-scalapack --download-suitesparse --download-triangle --download-zlib

Possible problem with ex19 running with mumps, diffs above
