This PR implements morsel-driven execution for Parquet files in DataFusion, enabling row-group level work sharing across partitions to mitigate data skew. Key changes: - Introduced `WorkQueue` in `datafusion/datasource/src/file_stream.rs` for shared pool of work. - Added `morselize` method to `FileOpener` trait to allow dynamic splitting of files into morsels. - Implemented `morselize` for `ParquetOpener` to split files into individual row groups. - Cached `ParquetMetaData` in `ParquetMorsel` extensions to avoid redundant I/O. - Modified `FileStream` to support work stealing from the shared queue. - Implemented `Weak` pointer pattern for `WorkQueue` in `FileScanConfig` to support plan re-executability. - Added `MorselizingGuard` to ensure shared state consistency on cancellation. - Added `allow_morsel_driven` configuration option (enabled by default for Parquet). - Implemented row-group pruning during the morselization phase for better efficiency. Tests: - Added `parquet_morsel_driven_execution` test to verify work distribution and re-executability. - Added `parquet_morsel_driven_enabled_by_default` to verify the default configuration.
