IMPALA-11269: Combine log entries of column accesses in the same table

This patch consolidates the Ranger audit log entries of column accesses
granted by the same policy for columns in the same table when a query is
successfully authorized.

Testing:
 - Revised the expected results in the existing FE tests related to
   Ranger audit log due to this patch.
 - Added a new test case to verify we do not combine Ranger audit log
   entries of column accesses granted by different policies even though
   those columns belong to the same table.
 - Added two new test cases to verify we won't have duplicate Ranger
   audit log entries if a column appears multiple times in a query.

> Currently Impala produces one Ranger audit log entry for each column of a table accessed in a query. We should consider consolidating the audit log entries associated with the same table so that we only produce one audit log entry for the columns associated with the same table.
