Add option for mysqldump to read data as of specific timestamp from system-versioned tables

Details

    Description

      It would be great to have an option for mysqldump to read data as of specific timestamp from system-versioned tables. One should just use:

      SELECT * FROM <t> FOR SYSTEM_TIME AS OF TIMESTAMP '...';

      Instead of simple SELECT for such tables if the option is provided.

      I think it makes sense to implement this separately from MDEV-16029

            Comment [ h3. Security precaution
            Should we allow function calls as {{--asof-time}} parameter, like:
            {code}
            mysqldump '--asof-time=NOW()' test
            {code}
            ?
