IMPALA-14937: (part 2) Enable MERGE for Iceberg V3
This is the second part of a multi-part implementation adding MERGE
support for Iceberg V3 tables with deletion vectors. This change enables
MERGE for Iceberg V3 tables, IcebergMergeQueryGenerator is extended with
V3 row-lineage support, the format-version gate is bumped to V3.
The getShuffleExprs method is adapted to handle unpartitioned cases
correctly as each data file must be referenced by only one deletion
vectors, previously MERGE was allowed to create multiple delete files
for each data file.
Testing:
- added iceberg-v3-merge.test
