Support precision of LocalZonedTimestampType in blink planner
URL: https://github.com/apache/flink/pull/10399
 
 
   ## What is the purpose of the change
   
   Since FLINK-14080 introduced an internal representation(SqlTimestamp) of

replace current long with SqlTimestamp, and let blink planner support precision 
of LocalZonedTimestampType
