Zoltan Borok-Nagy 3f51a6a761 IMPALA-11051: Add support for 'void' Iceberg partition transform ...

Iceberg recently added a new partition transform called 'void':
https://iceberg.apache.org/#spec/#partition-transforms

This patch adds support for this transform.

When the user wants to drop a column from the partition spec,
the VOID transform should be used instead of just omitting
the column. Simply omitting the column might cause problems when
the metadata table is being queried (currently only supported
by other engines).

Testing
 * added SHOW CREATE TABLE test
 * added e2e test
