This is needed so we can remove ice (solid) runoff but not river (liquid) runoff.

This merge also removes totalRemoved*RunoffFlux variables. These fields are computed incorrectly (they are missing areaCell) and are not currently used for anything within MPAS-Ocean or any diagnostics.

This is part of the design: https://acme-climate.atlassian.net/wiki/spaces/PSC/pages/4210098268/Design+Document+Data+iceberg+and+ice-shelf+melt+flux+patterns+for+E3SM+spin-up+runs
This is a high priority for the Polar team.

See E3SM-Ocean-Discussion#105 for some useful discussion and testing

[NML]
[non-BFB] for simulations with DIB and either DISMF or PISMF (data icebergs and data or prognostic melt rates)
[BFB] for simulations with snow-capping (e.g. current E3SM v3 production runs)

@jonbob, could you double check that I haven't messed up the namelist propagation from Registry to E3SM?

@xylar -- the bld files all look perfect. Thanks!

I ran e3sm_cryo_developer on chrysalis and got NML DIFFs for all of the tests, but these were otherwise BFB:

  ERS_Ld5.T62_oQU240wLI.GMPAS-DIB-IAF-PISMF.chrysalis_intel
  ERS_Ld5.T62_oQU240wLI.GMPAS-DIB-IAF-DISMF.chrysalis_intel
  PEM_Ln5.T62_oQU240wLI.GMPAS-DIB-IAF-DISMF.chrysalis_intel
  PEM_Ln5.T62_oQU240wLI.GMPAS-DIB-IAF-PISMF.chrysalis_intel
  PET_Ln5.T62_oQU240wLI.GMPAS-DIB-IAF-DISMF.chrysalis_intel
  PET_Ln5.T62_oQU240wLI.GMPAS-DIB-IAF-PISMF.chrysalis_intel

only

SMS_D_Ld1.TL319_IcoswISC30E3r5.GMPAS-JRA1p5-DIB-PISMF.chrysalis_intel.mpaso-jra_1958

was non-BFB. But maybe that makes sense -- CORE-II forcing doesn't have any frozen runoff

A test of

ERP_Ld3.ne30pg2_r05_IcoswISC30E3r5.WCYCL1850.chrysalis_intel.allactive-pioroot1

also passes but has a NML DIFF, as expected

Separate removal of Antarctic river and ice runoff

This is needed so we can remove ice (solid) runoff but not river
(liquid) runoff.

This merge also removes totalRemoved*RunoffFlux variables. These fields
are computed incorrectly (they are missing areaCell) and are not
currently used for anything within MPAS-Ocean or any diagnostics.

[NML] for all configurations with mpas-ocean
[non-BFB] only for simulations with JRA forcing, DIB and either DISMF
          or PISMF (data icebergs and data or prognostic melt rates)
