Aman Sinha 6894085e4e IMPALA-11030: Fix incorrect creation of common partition exprs
When there are 2 or more analytic functions in an inline view
and at least one of them does not have a partition-by expr,
we were previously still populating the commonPartitionExprs
list in AnalyticInfo. This common partition expr was then
used during the auxiliary predicate creation when the outer
query has a predicate on partition-by column. This leads to
wrong result because the auxiliary predicate is pushed down
to the table scan. While pushing down predicate on a
partitioning column is okay if all the analytic functions
contain that partitioning column, it is not correct to do
this when at least one analytic function does not have that
partitioning column.

This patch fixes the wrong result by ensuring that the
AnalyticInfo's commonPartitionExprs is empty if at least
one analytic function does not have partitioning exprs.

Testing:
 - Added new planner test and e2e test for row_num
   analytic function
