array_contains returns null instead of false for empty array with literal value

[andygrove]

Description

array_contains(arr, 2) returns null instead of false when arr is an empty array (array()).

How to Reproduce

CREATE TABLE test(arr array<int>) USING parquet;
INSERT INTO test VALUES (array());
SELECT array_contains(arr, 2) FROM test;

Expected: false
Actual (Comet): null

Expected Behavior

Comet should return false for array_contains when the array is empty, matching Spark's behavior.
