Juan 15/11/2023:configure, Upgrade version to MNH-V5-5-OPENACC-FFT-1 & compiler CCE/16.0.0 for ADASTRA

Juan 14/11/2023:init_mnh.f90, add initialisation of GPU halo with INIT_HALO_D , to avoid some potentiel null pointer a first GET_HALO_D call

Juan 14/11/2023: rain_ice_fast_ri.f90, Bug/data not present with CCE/16.0.1 around where -> add mnh_expand_where to bypass the bug (other where have already been transformed this way)

Juan 27/10/2023:Rules.LXgfortran.mk, managed defaut value CC=gcc + FC=gfortran <=> default wrong old CC=cc + FC=f77

Juan 27/10/2023:prep_ideal_case.f90, for OPENACC add initialisation of MNH_ALLOC_ZWORK+INIT_HALO_D => PREP_IDEAL work with VER_USER=ZSOLVER version

Juan 26/10/2023:ZSOLVER/tensorproductmultigrid_Source/*.f90 , replace double_precision -> MNH_REAL for enable compilation in REAL*4 for GPU

Juan 24/10/2023:ZSOLVER/dyn_sources.f90 , for cce/16.0.0 , add new present_cr directive to avoid FALSE RECURRENCE on GPU

Juan 24/10/2023:MNH/*.f90 , for cce/16.0.0 , add new present_cr directive to avoid FALSE RECURRENCE on GPU

Juan 24/10/2023:Rules.LXcray.mk , For cce/16.0.0 add EC_CONF= -DCMAKE_BUILD_TYPE="RELEASE" to avoid problem with -Gfast option removed from compiler

Juan 16/10/2023:Rules.LXnvhpc2202.mk, add example of LDFLAGS for  executable directly linked with MAP lib

Juan 16/10/2023:Makefile, for Arm compiler , remove DIR_ECCODES_BUILD after installation , to avoid "empty" main executable

Philippe 10/10/2023: tridz: remove wrong condition (was there to prevent problem with ZSOLVER; correct condition is based on HPRESOPT)

Philippe 26/09/2023: ini_modeln: allocate XBFB to zero size if not used (useful to prevent crash with OpenACC)

Philippe 19/09/2023: OpenACC: PREP_IDEAL_CASE: put some data on GPU (remark: not expected to work on GPU yet)

Philippe 18/09/2023: FLAT_INV: fix for NOOPENACC (deallocate ZBAND_YT and ZBAND_YRT only if allocated)

Philippe 12/09/2023: remove key MNH_PGI (not useful anymore, was to workaround an bug in very old version of PGI compiler)

(cherry picked from commit a7413073)

Philippe 29/08/2023: OpenACC: work around for a problem with NVHPC 23.7 (not present in older versions)

(cherry picked from commit ce39d7dc)

Juan 25/07/2023:ZSOLVER/advection_metsv.f90 , add cpp key MPIVIDE to compile with gfortran+GPU nvidia or amd
