v12 shocmf updates

[narnold1]

SHOCMF updates. Adds v2.0 of double gaussian PDF, removes CLASP and LTS options from EDMF, various stability improvements and code cleanup. 0-diff with exception of turb_internal_rst: new internals were added, used by SHOC only.

@narnold1 GNU has an issue but I think it's been fixed in upstream v12. When ready, you can press the "Update branch" button and the CI should be happy.

@narnold1 The build error seems to be saying something is missing in the call to partition_dblgss. There aren't enough arguments in the call.

The call does:

​            call partition_dblgss(fQi,          &
                                  TEn,          &
                                  QVn,          &
                                  QCn,          &
                                  0.0,          &
                                  ZL,           &
                                  PL*100.,      &
...

but the subroutine has:

subroutine partition_dblgss( fQi,          &  ! IN
                              tabs,         &
                              qwv,          &
                              qc,           &  ! OUT
                              qsat,         &
!                              qi,           &
                              omega,        &  ! IN
                              zl,           &
                              pval,         &

So it's either missing qsat or omega. Something is being passed in as 0.0 but I'm not sure what.

[narnold1]

Yes, "qsn" should be passed in after QCn. omega is passed in as 0.

My tests reverting the negative protection change show this PR passes:

1. All regression tests
2. 0-inc replay test
3. All restarts from AMIP and Replay modes are 0-difference EXCEPT:
   • turb_import_checkpoint long_name changed from "surface geopotential height" to "surface geopotential"
   • turb_internal_checkpoint added variables: MFAW, QTFLXMF, SLFLXMF
