IMPALA-4863: Correctly account the file type and compression codec

If a scan range is filtered at runtime the scan node skips reading
the range and never figures out the underlying compression codec used
to compress the files. In such a scenario we default the compression
codec to NONE which can be misleading. This change marks these files
as filtered in the scan node profile

e.g. - File Formats: PARQUET/SNAPPY:364 PARQUET(Filtered):1460
