Summary
chore: enable Lz4Raw for parquet reading compatibility
Re-enable Lz4Raw compression support for the data written by legacy databend-query in the reading path
to maintain compatibility with existing objects that were compacted with parquet Lz4Raw (but marked as databend LZ4 previously).
Note: The writing path remains unchanged - no new Lz4Raw compressed data will be generated.
