IMPALA-14937: (addendum) Fix NPE on shuffle expression creation for Iceberg V3
MERGE statements
isPartitioned() checks all historical partition specs, not just the
current default spec. A table that was created with a non-VOID partition
spec and then evolved to all-VOID still returns true from
isPartitioned().
The fix guards the partitioned V3 shuffle path with an additional
!targetPartitionExpressions_.isEmpty() check so that a table whose
current spec has no active partition fields uses PARTITION__SPEC__ID
and ICEBERG__PARTITION__SERIALIZED for shuffling.
Testing:
- Added a new test case to iceberg-v3-merge.test.
