Confirmation messages for `insert` and `alter` missing info regarding records, duplicates, and warnings

dolt
```
tmp/main*> insert into set_table values(0, 'abc,def'),(1,'def'),(2,'ghi');
Query OK, 3 rows affected (0.01 sec)
tmp/main*> alter table set_table modify column c0 varchar(100);
Query OK, 0 rows affected (0.01 sec)
```

mysql
```
mysql> insert into set_table values (0, 'abc,def'),(1, 'def'),(2,'ghi');
Query OK, 3 rows affected (0.00 sec)
Records: 3 Duplicates: 0 Warnings: 0

mysql> alter table set_table modify column c0 varchar(100);
Query OK, 3 rows affected (0.03 sec)
Records: 3 Duplicates: 0 Warnings: 0
```

Note that the number of rows affected for the `alter` statement is also different (filed as separate issue in #9606)

No files, tests, or entry points are named. Start by locating the code that formats confirmation messages for INSERT and ALTER TABLE statements, then compare its output with the MySQL examples; done means both messages report Records, Duplicates, and Warnings while preserving the separate row-count issue in #9606.
