MaterializeMySQL: Reconnect on Lost MySQL Connection

MaterializeMySQL: attempt to reconnect to MySQL if the connection is lost. #20961 (Håvard Kvålen).
MaterializeMySQL engine now attempts to automatically reconnect to MySQL if the connection is lost.

Why it matters

This feature improves the reliability and stability of the MaterializeMySQL engine by handling MySQL connection interruptions transparently, reducing manual intervention and data synchronization issues for users.

How to use it

The reconnection behavior is applied automatically when using the MaterializeMySQL engine; no additional configuration is needed. Simply use the engine as usual and it will attempt to reconnect if the MySQL connection drops.
