Rationale for this change
This PR implements comparison logic for Union arrays against opaque (non-union) arrays in the
ordkernelWhen comparing a union to an opaque array, the comparison first checks if the union's type id matches the opaque array's type, then compares the actual values if types align. This provides a consistent ordering where union variants are ordered by their type id relative to the opaque type
