IMPALA-11950: Planner change for Iceberg metadata querying
This commit extends the planner with IcebergMetadataScanNode which will
be used to scan Iceberg metadata tables (IMPALA-10947). The scan node is
only implemented on the frontend side in this patch, the backend part
will be developed in IMPALA-11996.
To avoid executing the plan there is a hardcoded condition, it is after
the explain part, so the change remains testable with EXPLAIN queries.
Testing:
- Added planner tests
