Added timestamp function for MySQL compatibility

Added function timestamp for compatibility with MySQL. Closes #54275. #54639 (Nikolay Degterinsky).
Added the timestamp function to ClickHouse for compatibility with MySQL.

Why it matters

This feature provides users migrating from MySQL or working with MySQL-compatible queries a familiar timestamp function, improving ease of adoption and query portability between the two database systems.

How to use it

Simply use the timestamp function in your SQL queries as you would in MySQL. It is available by default after upgrading ClickHouse to the version that includes this feature.
