Fix macro typo: MLK_UNION_OR_STRUCT => MLD_UNION_OR_STRUCT

- This commit fixes a error cause by macro typo in .clang-format
    where MLK_UNION_OR_STRUCT should be
    MLD_UNION_OR_STRUCT. This typo was detected after
    extending the macro checker to catch wrongly ported
    MLK_XXX/MLKEM_XXX macros.
