**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.

/** Previously, these constants were located in one enum.
  * But in this case there is a problem: when you add a new constant, you need to recompile
  * all translation units that use at least one constant (almost the whole project).
  * Therefore it is made so that definitions of constants are located here, in one file,
  * and their declaration are in different files, at the place of use.
  *
  * Later it was converted to the lookup table, to provide:
  * - errorCodeToName()
  * - system.errors table
