### What problem does this PR solve? Forward-port the Parquet V2 direct predicate work from #66149 to master. The V2 reader previously materialized decoded columns before evaluating many comparison, runtime filter, compound, and TopN predicates. This adds direct dictionary, raw fixed-width, raw binary, and converted-value filtering while preserving nullable and conversion semantics. It also bounds reusable predicate scratch memory, avoids wide sparse dummy-block allocations, keeps dynamic TopN residual evaluation correct across bound updates, and normalizes TopN nullable filter results for the master expression type contract. ### Validation - Built doris_be_test with 128-way parallelism - Passed 224 tests across DataTypeSerDeParquetTest, RuntimePredicateTest, ParquetRuntimeFilterDirectReaderTest, ParquetScanTest, and ParquetV2NativeDecoderTest -- This is an automated message from the Apache Git Service.
