Add Backup and Restore Support for Tables with KeeperMap Engine

Add support for backing up and restoring tables using KeeperMap engine. #56460 (Antonio Andelic).
Add support for backing up and restoring tables that use the KeeperMap engine in ClickHouse.

Why it matters

The feature enables users to perform backup and restore operations on tables utilizing the KeeperMap engine, which previously lacked such support. This solves the problem of data protection and recovery for these tables, enhancing reliability and operational safety.

How to use it

Users can backup and restore KeeperMap engine tables using the existing BACKUP and RESTORE commands in ClickHouse, now extended to include this table engine without requiring additional configuration.
