Implement landfast ice test case for Icepack

[eclare108213]

Bring Mathieu Plante’s forcing and diagnostic changes into the Icepack repository as a test case.

1. Added forcing from GEM atmospheric model.
2. Added column that is initialised with data from SIMBA buoys.
3. New diagnostics related to the ice mass balance.

See Icepack issue #481 and Mathieu's code: https://zenodo.org/records/10845358.

Note:
Parameterization modifications are also included in the code above, which can be considered in separate PRs:

1. Added porosity criteria for the snow flooding parameterization in the mushy layer thermodynamics.
2. Added free-board dependency for the snow flooding rates (mushy layer).
3. Modified mushy-layer congelation parameterization. This item was completed in Alternative congelation formulation following Plante et al. 2024 #494.
