Add MySQL Compatibility for SHOW ENGINES Query Support

Add support for SHOW ENGINES query for MySQL compatibility. #45859 (Filatenkov Artur).
Added support for the SHOW ENGINES query to enhance MySQL compatibility in ClickHouse.

Why it matters

This feature addresses the need for better interoperability with MySQL tools and workflows by enabling the SHOW ENGINES query. It helps users identify available table engines in ClickHouse similarly to MySQL, simplifying migration and integration processes.

How to use it

Users can execute the SHOW ENGINES query directly in ClickHouse, just like in MySQL, to list supported table engines. No additional configuration is required.
