stiga-huang 47309d14ca IMPALA-12204: Fix redundant codegen info added in subplan profiles ...

The SUBPLAN node will open its right child node many times in its
GetNext(), depending on how many rows generated from its left child. The
right child of a SUBPLAN node is a subtree of operators. They should not
add codegen info into profile in their Open() method since it will be
invoked repeatedly.

Currently, DataSink and UnionNode have such an issue. This patch fixes
them by adding the codegen info to profile in Close() instead of Open(),
just like what we did in IMPALA-11200.

Tests:
 - Add e2e tests
