Enhancement
Increase the range of Timestamp column, to 3001-01-19.
See https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html#function_unix-timestamp
Prior to MySQL 8.0.28, the valid range of argument values is the same as for the TIMESTAMP data type: '1970-01-01 00:00:01.000000' UTC to '2038-01-19 03:14:07.999999' UTC. This is also the case in MySQL 8.0.28 and later for 32-bit platforms.
For MySQL 8.0.28 and later running on 64-bit platforms, the valid range of argument values for UNIX_TIMESTAMP() is '1970-01-01 00:00:01.000000' UTC to '3001-01-19 03:14:07.999999' UTC (corresponding to 32536771199.999999 seconds).
It should be fairly easy in TiDB, since it is stored in the same format as DateTime, bit shifted YYYY MM DD HH MM SS . FRAC, but there are check to keep it in the same range as signed 32-bit time_t to be compatible with MySQL.
