Cleanup a few places where the code returned a null array but it would be a bit cleaner and faster to return a typed scalar null instead. ## Which issue does this PR close? Does not close an issue; this cleanup was mentioned in the code review for #20361 ## Rationale for this change Returning a typed scalar null should be preferred to returning a null array: it still has type information, and avoids materializing an all-null array. The downstream consumer can always materialize the equivalent array if they want to. ## What changes are included in this PR? Cleanup five instances of this pattern. ## Are these changes tested? Yes. No new test cases possible/warranted. ## Are there any user-facing changes? No. -- This is an automated message from the Apache Git Service.
