Please answer these questions before submitting your issue. Thanks!
I want to make sure two tables both be created successfully, if one failes, rollback the whole transaction, but I found that transaction won't rollback CREATE TABLE statements.

1. Minimal reproduce step (Required)

start transaction;
create table t0(c0 int);
rollback;
select * from t0;

2. What did you expect to see? (Required)

> start transaction;
Query OK, 0 rows affected (0.00 sec)
> create table t0(c0 int);
Query OK, 0 rows affected (0.16 sec)
> rollback;
Query OK, 0 rows affected (0.00 sec)
> select * from t0;
ERROR 1146 (42S02): Table 'd0.t0' doesn't exist

3. What did you see instead (Required)

> start transaction;
Query OK, 0 rows affected (0.00 sec)
> create table t0(c0 int);
Query OK, 0 rows affected (0.16 sec)
> rollback;
Query OK, 0 rows affected (0.00 sec)
> select * from t0;
Empty set (0.01 sec)

4. What is your TiDB version? (Required)

this should be the same behaviour as MySQL https://dev.mysql.com/doc/refman/8.0/en/implicit-commit.html
