morrySnow abdf56bfa5 [fix](Nereids) wrong result of group_concat with order by or null args (#16081)
1. signatures without order element are wrong
2. signature with one arg is miss
3. group_concat should be NullableAggregateFunction
4. fold constant on fe should not fold NullableAggregateFunction with null arg

TODO
