URL: https://github.com/apache/hive/pull/6698
### What changes were proposed in this pull request?
Check [HIVE-29815](https://issues.apache.org/jira/browse/HIVE-29815)
This PR updates `CopyOnWriteDeleteRewriter.java` to explicitly select and
preserve `ROW__LINEAGE__ID` and `LAST__UPDATED__SEQUENCE__NUMBER` when
rewriting files during a Copy-On-Write DELETE operation on Iceberg V3 tables.
### Why are the changes needed?
Currently, when a user deletes a row in COW mode, the surviving rows are
rewritten into a new file without their original lineage metadata. As a result,
they get assigned brand new lineage IDs and sequence numbers
### Does this PR introduce _any_ user-facing change?
Yes
### How was this patch tested?
With q file and on spark engine as well
