MaterializeMySQL: Add Minmax Skipping Index for _version Column

Why it matters

This feature improves query performance by enabling efficient data skipping based on the _version column, reducing the amount of data read during queries on replicated MySQL tables.

How to use it

The minmax skipping index on the _version column is automatically added in the MaterializeMySQL engine; users do not need to manually enable it. Queries will benefit from improved performance when filtering on the _version column.
