[JDBC-V2] setMaxRows() doesn't work when `result_overflow_mode` is readonly

[chernser]

Description

The method com.clickhouse.jdbc.StatementImpl#setLargeMaxRows uses result_overflow_mode to hard limit returned result set. This approach may not work when this setting is readonly for users.

It should be configurable to not touch the setting.
