IMPALA-12387: PartialUpdates is misleading for LOCAL filter
In filter table, PartialUpdates is intended to mark if coordinator
receive only partial update from contributing fragments. This can be
misleading for LOCAL filter in column "Min value", "Max value", and
"In-list size", because LOCAL filter does not aggregate in coordinator
anymore. Thus, coordinator does not receive any filter update.
This patch mark such column value as "LOCAL" if no global aggregation is
expected in coordinator.
Testing:
- Pass core tests.
