PSyclone support for user-defined kernels that act on DoFs

In the past PSyclone didn't support user-defined kernerls that act on DoFs. As of PSyclone 3.0.0, this has been resolved (see PSyclone Issue #1351). Furthermore, as of PSyclone 3.1.0 user-defined DoF kernels should also work with field vectors (see PSyclone Issue #2892). This should allow the removal of

• invoke_convert_cart2sphere_vector
• invoke_pointwise_convert_xyz2llr

found in components/science/source/psy/sci_psykal_builtin_light_mod in LFRic core. This is being addressed in the linked LFRic core #4535 and LFRic apps #575 tickets.

Currently, invoke_convert_cart2sphere_vector is being called in LFRic apps
