fix: Incorrect comparison in some cases with filtered list/array columns

[nameexhaustion]

Fixes #20165

[nameexhaustion]

empty chunks 🥲

[ritchie46]

Ai, how do we get those?

[nameexhaustion]

The filter goes through a the binary_unchecked_same_type kernel, which takes the filter op as Fn(Array, Array) -> Array - so if the predicate was false for an entire chunk it ends up empty

Lines 535 to 541 in 8c39bb9

	let chunks = lhs
	.downcast_iter()
	.zip(rhs.downcast_iter())
	.map(|(lhs_arr, rhs_arr)| op(lhs_arr, rhs_arr))
	.collect();
	let mut ca = lhs.copy_with_chunks(chunks);
