IMPALA-10763: Min/max filters should be enabled on Z-order sorted columns

This patch enables min/max filtering on Z-order sorted by columns by
default.

Since the column stats for a row group or a page is computed from the
column valuess stored in the row group or the page, the current
infrastructure for min/max filtering works for the Z-order out of box.
The fact that these column valuess are ordered by Z-order is
orthogonal to the work of min/max filtering.

Testing [TBD]
  1. New z-order related sort column tests in
     overlap_min_max_filters_on_sorted_columns.test;
  2. core-test
