Don't Allow Storage Creation with Unknown Data Format

Don't allow to create storage with unknown data format. #37450 (Kruglov Pavel).
ClickHouse now prevents creating storage with unknown data formats to ensure data integrity and correctness.

Why it matters

This feature stops users from inadvertently creating table storages using unsupported or unrecognized data formats. It improves reliability by catching configuration errors early and avoiding runtime issues caused by invalid data formats.

How to use it

When creating a new storage, ensure that the data format specified is supported by ClickHouse. The system will reject creation commands that try to use an unknown data format, so only use recognized formats as listed in the documentation.
