 The main issue is the order of the loop when we need to start from mikt(ji,jj). To order the loop jk/jj/ji instead of jj/ji/jk, the first solution is to create a wmask, wumask and wvmask in order to mask all the variable at w point properly. Like this the mask system can be applied at the top as it is done at the bottom.
 
-In some place we also need to change the order between the initialisation of the interior value and surface value (3D loop jj/ji/jk => 2D loop jj/ji with mikt in it)

-Duplication of some routine are done in order to keep the same performance than the one before the merge if ln_isfcav is false (hpg_sco => hpg_isf and zps_hde => zps_hde_isf and the old one are restore)

-Commit 23/02 : remove all 3 d loop + some missing flag and add 3 masks (wmask, wumask, wvmask). Sette OK and not change in the solution of sette. For ORCA1 (acc), to have the same results we need to force the zgr_isf (bug from the trunk move to this subroutine) and this subroutine is only activated if ln_isfcav. Need also to force zps_hde_isf and hpg_isf as we restore hpg_sco and move the current one to hpg_isf.

 How ice shelf cavity is coded need to have e3t(jk) = (gdepw(jk+1)-gdepw(jk)) for the pressure gradient. The start point for the water column is risfdep(ji,jj) and not 0. So, level in depth can be not aligned (ie can have a different gdep3w with the default e3t definition).
