Support FORMAT Clause in BACKUP and RESTORE Queries

Why it matters

This feature allows users to specify the backup format explicitly when creating or restoring backups, providing greater flexibility and control over backup storage and interoperability.

How to use it

Users can specify the backup format in their queries using the FORMAT clause within BACKUP and RESTORE commands. For example:

BACKUP TABLE my_table TO 'backup_path' FORMAT <format_name>;
RESTORE TABLE my_table FROM 'backup_path' FORMAT <format_name>;
