Added system.backups update for task progress tracking

Added update system.backups after every processed task to track the progress of backups. #46989 (Aleksandr Musorin).
Added automatic updates to system.backups after processing each backup task to enable tracking of backup progress.

Why it matters

This feature solves the problem of not having real-time visibility into the progress of backups. By updating system.backups after every processed task, users can monitor backup status and progress directly within ClickHouse, improving reliability and operational transparency.

How to use it

The feature is enabled automatically when using ClickHouse backups. Users can query the system.backups system table to view the updated backup progress information after each task completes.
