IMPALA-9745: Propagate source type when doing constant propagation
When doing constant propagation the source type was not being
propagated to the target expression leading to an analysis failure.
The behavior is most easily reproducible with STRING to TIMESTAMP
conversion in the presence of other predicates.
This patch fixes this by adding an implicit cast if needed for such
cases.
Testing:
- Added planner test and ran other planner tests
- Added end-to-end test
