IMPALA-11350 implemented the FILE__POSITION virtual column for Parquet files. This ticket does the same but for ORC files. Note, that for full ACID ORC tables there have already been an implementation of row__id that could simply be re-used for this ticket. Testing: - TestScannersVirtualColumns.test_virtual_column_file_position_generic is changed to run now on ORC as well. I don't think further testing is required as this functionality has already been there for row__id we just re-used it for FILE__POSITION.
