IMPALA-11081: Fix incorrect results in partition key scan
This patch fixes incorrect results caused by short-circuit partition
key scan in the case where a file contains multiple blocks.
IMPALA-8834 introduced the optimization that generating only one
scan range that corresponding to the first block per file, backends
only read footers for parquet/ORC files, which leads to incorrect
results if the first block doesn't include a file footer. This bug
is fixed by returning a scan range corresponding to the last block
to make sure it contains a file footer.
Testing:
- Added an e2e test to verify the fix.
- Ran TestPartitionKeyScans to make sure no regressions.
