   ### What changes were proposed in this pull request?
   
   Change `withTimeZone` for Cast to only put the time zone if needed for 
casting.
   
   ### Why are the changes needed?
   
   Analyzer is overeager, so it produces a stronger result (always put time 
zone for Cast) then needed for Cast to be marked as resolved (only need 
timezone if it is needed for cast). This causes problems when reanalyzing plan 
for single-pass analyzer.

   No.
   
   
   ### How was this patch tested?
   
   cte-recursion with single pass, existing CIs.
