Description
PSyclone doesn't currently support the option for scalar arguments in intergrid kernels, which was needed in [LFRic #3999](https://code.metoffice.gov.uk/trac/lfric/ticket/3999) The following PSyKAl-lite functions exist in LFRic apps because of this -
* `invoke_prolong_multidata_scalar_kernel_type`
* `invoke_restrict_multidata_scalar_kernel_type`
* `invoke_prolong_multidata_linear_kernel_type`
which are found in LFRic apps `science/gungho/source/psy/psykal_lite_mod`. These are all called by `science/gungho/source/algorithm/core_dynamics/intermesh_mappings_alg_mod.x90`. The corresponding PSyclone ticket for this is [PSyclone #2504](https://github.com/stfc/PSyclone/issues/2504).

Research direction
Start with PSyclone issue #2504, then inspect the listed PSyKAl-lite functions in science/gungho/source/psy/psykal_lite_mod and their calls from science/gungho/source/algorithm/core_dynamics/intermesh_mappings_alg_mod.x90. Confirm the required scalar-argument behavior and identify how the three existing functions depend on that support. Done means the corresponding PSyTran/LFRic workflow no longer requires these workaround functions.
