Change some of our grids to use the MOM land/ocean mask at t232/t233

CESM3 has removed the POP ocean model, and now only has the MOM ocean model with the t232 grid. To be consistent with this change we should change our mizuRoute grid that use the t13 land/ocean mask to the t232 mask. However, there are some caveats here:

- The t232 grid is at a course resolution there may be science reasons to have a higher resolution land/ocean mask
- We'll have to add these new grids to ccs_config
- We'll need to update the tests to use the new grids

Since, this entails a bit of work to do, I'm not sure we should do it now for the CESM3 release. But, as we eventually want to couple mizuRoute to MOM -- we will need to do this eventually.

The grids that would need to change are:

hcru_hcru_rMERIT_mt13
hcru_hcru_rHDMA_mt13
hcru_hcru_rHDMAlk_mt13
f09_f09_rMERIT_mt13
f09_f09_rHDMA_mt13
f09_f09_rHDMAlk_mt13
f19_f19_rMERIT_mt13
f19_f19_rHDMA_mt13
f19_f19_rHDMAlk_mt13

to:

hcru_hcru_rMERIT_mt232
hcru_hcru_rHDMA_mt232
hcru_hcru_rHDMAlk_mt232
f09_f09_rMERIT_mt232
f09_f09_rHDMA_mt232
f09_f09_rHDMAlk_mt232
f19_f19_rMERIT_mt232
f19_f19_rHDMA_mt232
f19_f19_rHDMAlk_mt232

Definition of done:

- [ ] ESMCI/ccs_config_cesm#209
- [ ] Change tests to use _mt232
- [ ] Remove the _mt13 aliases from ccs_config
