Correct a bug that G%gridLonT/G%gridLatT were not using global indexing in outputing extreme surface information.
Previously extreme surface message is triggered when `sea_lev` is smaller than or **equal** to ocean topography: sfc_state%sea_lev(i,j) <= -G%bathyT(i,j) - G%Z_ref The equality is innocuous for a non-zero minimum thickness (Angstrom/=0), but it can be problematic for true zero thickness. Besides, there is the fourth criterion in this check: sfc_state%sea_lev(i,j) + G%bathyT(i,j) + G%Z_ref < CS%bad_val_col_thick This is supposed to allow a user-specified tolerance (default=0.0), which should be a more stringent check when the tolerance is larger than zero. The equality from the first check contradicts this logic.
Fix a bug that sea surface height averaged over every dynamic time step (SSH_inst) is not outputted correctly.

This PR contains three minor fixes related to SSH diagnostics and checks, which address the following issues:
