IMPALA-12153: Parquet STRUCT reader should fill position slots

Before this patch the Parquet STRUCT reader didn't fill the
position slots: collection position, file position. When users
queried these virtual columns Impala was crashed or returned
incorrect results.

The ORC scanner already worked correctly, but there was no tests
written for it.

Test:
 * e2e tests for both ORC / Parquet

> SET expand_complex_types=True;
> select file__position, * from complextypestbl;{noformat}
