[Bug](agg-state) fix agg state inner type not conversioned (#50418)
### What problem does this PR solve?
drop table if exists t01;
create table t01(id int, decimal_col agg_state<sum(decimal(20,6))>
generic) properties ("replication_num" = "1");
insert into t01 values (1, sum_state(10.1)), (1, sum_state(20.1)), (2,
sum_state(10.2)), (2, sum_state(11.0));
select sum_merge(decimal_col) from t01 group by id;
