FlyingOnion 551de3767c modify limit offset implement (#2188) 
Oracle and SQLServer specific: When `LIMIT OFFSET` function is needed, use `OFFSET <offset> ROWS FETCH NEXT <limit> ROWS ONLY` to replace legacy subquery.

SQLServer specific: When `ORDER BY` is not set and `OFFSET FETCH` is set, set `statement.orderStr` to `1` (`ORDER BY 1`). See [here](https://learn.microsoft.com/zh-cn/sql/t-sql/queries/select-order-by-clause-transact-sql?view=sql-server-ver16).

MySQL specific: When limit is 0 and offset > 0, use `LIMIT 9223372036854775807` ($2^{63}-1$). See comments [here](15d171ea55/internal/statements/query.go (L314)).
