[CALCITE-4805] Calcite should convert a small IN-list as if the user had written OR, even if the IN-list contains NULL

Since [CALCITE-373], Calcite has converted "x IN (1, 2)" to
"x = 1 OR x = 2" but it still converts "x IN (1, NULL)" to
"x IN (VALUES 1, NULL)". Now that some bugs have been fixed,
there's no longer any reason to treat lists with NULL any
differently.
