This requires some changes to user FORTRAN code

Pass PETSC_NULL_XXX_ARRAY when passing a NULL as an argument that is expecting an array
Pass PETSC_NULL_ENUM when argument returns an enum instead of PETSC_NULL_INTEGER
Pass arrays (and not scalar values) when the argument is expecting an array; this means replace, for example, the argument v with [v]
Use PetscObjectIsNull(obj) to check if the object is NULL, instead of obj == PETSC_NULL_XXX

The compiler will now automatically prevent you from using the wrong argument type for the first three bullets above
This will also require an update sowing with the new sowing branch this MR is using.

Plex Isoperiodic: Form closure_sf from face_sfs

The `point_sf` was (and is still) used to redirect local mesh points in
the face's closure to their "true" owner. ie. if a local vertex was
actually owned by another rank, then the closure should refer to that
rank.

The only major change here is that as we loop over face_sfs, we update
the `point_sf` to be the merger of `point_sf` and the previously found
closure_sf. This way, if two `face_sf` share a mesh point in their
face's closure, it gets "claimed" only once.
