Support writing version-hint file

Iceberg: support writing version-hint file. This closes #85097. #85130 (Konstantin Vedernikov).
Added support for writing a version-hint file in Iceberg table format within ClickHouse.

Why it matters

This feature addresses the need to improve compatibility and version tracking when working with Iceberg tables by writing a version-hint file. It helps users maintain consistency and manage Iceberg table versions more effectively.

How to use it

When using Iceberg tables in ClickHouse, the system now automatically writes a version-hint file during table operations, requiring no additional configuration from the user.
