IMPALA-12824: Removes the prettyprint_duration Built-in Function

Browse Source 
The prettyprint_duration function was originally
implemented in IMPALA-12824 to work with the workload
management tables which stored durations in integer
nanoseconds. These tables have changed to store decimal
seconds.

The prettyprint_duration function would have required a
large investment of time to make it work with decimal
values, and since the new format is more human readable
anyways, this function has been removed.
