Add Base Backup Name to system.backups and system.backup_log Tables

Why it matters

This feature provides users with clearer identification and tracking of backups by associating each entry in the system tables with the specific base backup name. It improves backup management and auditing capabilities.

How to use it

After updating to the new ClickHouse version, users can query the system.backups and system.backup_log tables to view the base backup name associated with each backup entry, without needing to enable any additional settings.
