[data-coupler-co2box] change transformation in namcouple generator when source and target grids are the same (e.g. GLOBAL for the co2box model)

Both DataCoupler and toyy_model are using the ece3/toy_model.py with a YAML input files. In addition, namcouple file for DataCoupller is generated automatically based on the YAML input. The CO2 E/C-modes are removed.

See merge request !4

Fixing all the issues that were raised in mr4. Also, preparing for future development: co2box & co2flux.

Resolved issue: Eliminating hard-coded MPI process type for partitioning, ensuring non-empty out_coupling_vars, and and no dependency on  MPI num_processes.

both datacoupler and ece3-toy-model are using the same /ece3-toy-model/toy_model.py, plus some clean up

WIP: DataCouplerPreprocessor.py is generating yaml_conf_ifs_toy_model.yaml that will be used be ifs_toy_model

WIP: cam couple is produced by the preprocessing script in a cleaner and more straightforward manner, prep work to remove type from YAMLUtils

Unifying execution of toy_model and datacoupler via /test/ directory with automated directory preparation and time stamping.

Merge both toy model types into a single general toy model with support for both toy model and datacoupler yaml

namcouple is generated by puscript before the call of Toy_model and Datacoupler. problem with commit-id:4208e78c is fixed

namcouple script is generating the namecouple in the style that was discussed (for each variable in a seperate parag.), eventhough it is not working with Oasis, it will follow up in next step

WIP: developing tools that is needed for generating namcouple, they will all move to a single script to generate namcouple before toy_model and datacoupler

WIP: harmonizing the general_toy_model.py with toy_model.py, still needs more adjustment. Extracting functions from DataCoupler to a seperate YAMLb script
