Column type for aggregate column created from select does not match MySQL

MySQL
```
mysql> create table t1 (i int);
Query OK, 0 rows affected (0.01 sec)

mysql> insert into t1 values (1);
Query OK, 1 row affected (0.00 sec)

mysql> create table t2 select sum(i) from t1;
Query OK, 1 row affected (0.01 sec)
Records: 1 Duplicates: 0 Warnings: 0

mysql> show create table t2;

+-------+------------------------------------------------------------------------------------------------------------------------------+
| t2 | CREATE TABLE `t2` (
`sum(i)` decimal(32,0) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci |
+-------+------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
```

Dolt
```
tmp/main*> create table t1 (i int);
Query OK, 0 rows affected (0.01 sec)
tmp/main*> insert into t1 values (1);
Query OK, 1 row affected (0.01 sec)
tmp/main*> create table t2 select sum(i) from t1;
Query OK, 1 row affected (0.01 sec)
tmp/main*> show create table t2;
+-------+------------------------------------------------------------------+
| Table | Create Table |
+-------+------------------------------------------------------------------+
| t2 | CREATE TABLE `t2` ( |
| | `sum(t1.i)` double NOT NULL |
| | ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_bin |
+-------+------------------------------------------------------------------+
1 row in set (0.00 sec)
```

Column is `decimal(32,0) DEFAULT NULL` in MySQL but `double NOT NULL` in Dolt. TODO added in dolthub/go-mysql-server#3182

Column name is fixed in dolthub/vitess#430
