IMPALA-15067: Add VariantValue and basic decoding functions
Adds the backend implementation for decoding VARIANT binary blobs:
- variant-value.h: Defines VariantMetadata (field name dictionary
parser) and VariantValue (value decoder with object/array accessors
and path navigation). Supports all variant physical types defined by
the Parquet Variant spec.
- variant-util.cc/h: Implements VariantToJson() which serializes a
variant (metadata + value blobs) to JSON. Supported types include
null, booleans, int8/16/32/64, float, double, decimal4/8/16,
short/long strings, objects, arrays, TIMESTAMPNTZ (micros), and
TIMESTAMPNTZ_NANOS. BINARY values are base64-encoded. TIMESTAMPTZ,
TIME, and UUID remain unsupported.
- variant-functions-ir.cc/h: Implements the variant_to_json(BINARY,
BINARY)->STRING builtin expression function.
Testing
- Unit tests covering metadata parsing, all primitive types, objects,
arrays, path navigation, and JSON serialization. Includes test cases
extracted from Hive-written and DuckDB Parquet test files for
cross-engine compatibility validation.
