zy-kkk 5a3107442a [feature](tvf) support query table value function (#34516 ) (#34640 )

This PR supports a Table Value Function called `Query`. He can push a query directly to the catalog source for execution by specifying `catalog` and `query` without parsing by Doris. Doris only receives the results returned by the query.
Currently only JDBC Catalog is supported.

Example:

```
Doris > desc function query('catalog' = 'mysql','query' = 'select count(*) as cnt from test.test');           
+-------+--------+------+------+---------+-------+
| Field | Type   | Null | Key  | Default | Extra |
+-------+--------+------+------+---------+-------+
| cnt   | BIGINT | Yes  | true | NULL    | NONE  |
+-------+--------+------+------+---------+-------+

Doris > select * from query('catalog' = 'mysql','query' = 'select count(*) as cnt from test.test');           
+----------+
| cnt      |
+----------+
| 30000000 |
+----------+
```
