planner: Plan Cache is not compatible with CTE

## Enhancement
If a query has any CTE tables, the optimizer will skip Plan Cache for this table, see the case below:
```
mysql> create table tt (a int);
Query OK, 0 rows affected (0.02 sec)

mysql> prepare st from "with tx as (select a from t) select * from tx;";
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> execute st;
Empty set, 1 warning (0.00 sec)

mysql> show warnings;
