**Describe the unexpected behaviour**
OFFSET can work without ORDER BY , but OFFSET FETCH cannot work without ORDER BY, and throw strange syntax error: `failed at 'FETCH' Expected FETCH`.

**How to reproduce**
* Clickhouse Version: `21.10.2.15`
* `CREATE TABLE test_fetch (a INT, b INT) ENGINE=MergeTree ORDER BY b;`
* `INSERT INTO test_fetch VALUES (1, 1), (2, 1), (3, 4), (1, 4), (5, 4), (0, 6), (5, 7);`
* `OFFSET` without `ORDER BY` works: `SELECT * FROM test_fetch OFFSET 3 ROW;`
* `OFFSET FETCH` with `ORDER BY` works: `SELECT * FROM test_fetch ORDER BY a OFFSET 3 ROWS FETCH FIRST 3 ROWS ONLY;`
* `OFFSET FETCH` without `ORDER BY`  does ***NOT*** work: `SELECT * FROM test_fetch OFFSET 3 ROWS FETCH FIRST 3 ROWS ONLY;`

**Expected behavior**
Same behavior or correct error message.
