In #29296 we uncovered some mismatches between how .contains and .is_in work between Map and List (and Array). I believe that Map handles all of these correctly, List differs in a couple of places due to legacy behavior, but also due to allowing inner nulls.
Investigate all differences here, related to mixed type keys, and keys of the same type but parameterized differently (different int width, float width, temporal resolution, time zone, decimal precision/scale,...)
