IMPALA-13770 added code to call Close() on
IcebergMergeCase::{output_exprs_,filter_conjuncts_}. However, these
expressions are created by IcebergMergeCasePlan, with pointers to the
expressions copied to possibly multiple IcebergMergeCase objects.
Therefore, although it does not cause errors in practice, it is better
to close the expressions in IcebergMergeCasePlan.
This change adds a Close() method to IcebergMergeCasePlan that closes
these expressions.
This patch also calls Close() on IcebergMergeSinkConfig::merge_action_
and IcebergMergeSink::merge_action_evaluator_, which were not closed
previously.
