MOM6: +Made 4 commits to support barotropic tides

  Made a series of 4 commits to help support the use of MOM6 in idealized
non-Boussinesq barotropic tide simulations.  All answers in existing test cases
are identical, but each of these 4 commits introduces changes to the
MOM_parameter_doc files.
MOM6 commit Hallberg-NOAA/MOM6@b509561
