IMPALA-11596: [DOCS] Document EXECUTE ROLLBACK functionality
Since IMPALA-11482 Impala supports the 'Alter Table Execute Rollback'
statement for Iceberg tables. Update the docs to cover this change.
The section on DESCRIBE HSTORY is expanded to include the output
columns, as this information is relevant to EXECUTE ROLLBACK.
The section on Cloning Iceberg tables is moved so that the sections
concerned with table history are adjacent.
TESTING:
- Built docs locally.

> Priority: Major
> Labels: impala-iceberg
> Fix For: Impala 4.3.0

>
> We should allow rolling back iceberg table's data to the state at an older
> table snapshot.
> Rollback to the last snapshot before a specific timestamp
> {code}
> ALTER TABLE ice_t EXECUTE ROLLBACK('2022-05-12 00:00:00')
> {code}
> Rollback to a specific snapshot ID
> {code}
> ALTER TABLE ice_t EXECUTE ROLLBACK(1111);
> {code}
> However, to revert a rollback we might need to be able to change the table's
> metadata_location property (like HIVE-26203).
