[INLONG-6373][Sort] Fix the time value when data type is datetime and timestamp

[EMsnap]

• Fixes [Bug][Sort] The time value is wrong when the data type is datetime and timestamp #6373

Motivation

fix time value when data type is datetime and timestamp

Modifications

fix time value when data type is datetime and timestamp

For timestamp, the debezium will first get the timestamp in the database time zone, and then convert it into UTC time zone.
So we only need to convert the timestamp in UTC time zone back to its origin timestamp

For zoned time stamp, we need to convert the zone time stamp using time zone set by user and the reformat the zoned timestamp into a timestamp ended with Z since flink JsonToRowDataConverters can only parse a zoned timestamp ended with UTC "Z" time zone.
