All strategies return the same result.
Those starting with Mask perform bitwise masking for each chunk of 64 values, including
computing expensive selection masks of fields: which fields masks must be computed is the
difference between them selection_mask 🔒 without_nulls_selected 🔒 Returns a bitmask where bits indicate if any id from without_nulls_ids exist in type_ids_chunk.
