    IMPALA-5014: Part 2: Round when casting decimal to timestamp
    
    When there are too many digits to the right of the dot in a decimal, we
    would always truncate when casting to timestamp. In this patch we change
    the behavior to round instead of truncating when decimal_v2 is enabled.
    
    Testing:
    - Added some EE tests, ran BE tests on my machine.
