[KYUUBI apache#3958] Fix Spark session timezone format

### _Why are the changes needed?_
The Spark session supports setting the time zone through `spark.sql.session.timeZone` and formatting according to the time zone, but `timestamp` does not use timezone, resulting in some incorrect results.

### _How was this patch tested?_
- [x] Add some test cases that check the changes thoroughly including negative and positive cases if possible

- [ ] Add screenshots for manual tests if appropriate

- [x] [Run test](https://kyuubi.apache.org/docs/latest/develop_tools/testing.html#running-tests) locally before make a pull request

Closes apache#3958 from cxzl25/fix_session_timezone.
