Enable MySQL/MariaDB Integration on macOS

Why it matters

This feature allows users running ClickHouse on macOS to connect and integrate with MySQL and MariaDB databases, solving the previous limitation where such integration was unavailable on macOS. It enhances cross-database workflows and data integration for macOS users.

How to use it

On macOS, users can now configure and use the MySQL/MariaDB table functions and external dictionaries as they would on other supported platforms, enabling seamless access to MySQL and MariaDB data sources.
