> Refactor SQL_GROUPED_MAP_PANDAS_UDF to be self-contained in read_udfs

> Key: SPARK-56477
> URL: https://issues.apache.org/jira/browse/SPARK-56477
> Project: Spark
> Issue Type: Sub-task
> Components: PySpark
> Affects Versions: 4.2.0
> Reporter: Yicong Huang
> Priority: Major
> Labels: pull-request-available
>
> As part of the PySpark eval type refactoring effort (SPARK-55388), the
> SQL_GROUPED_MAP_PANDAS_UDF processing logic should be made self-contained
> within read_udfs() in worker.py.
> Currently the logic is spread across the wrapper function
> wrap_grouped_map_pandas_udf(), the GroupPandasUDFSerializer, and the mapper
> block in read_udfs(). The refactoring should consolidate all UDF dispatch,
> verification, and conversion logic into an inline handler in read_udfs(),
> using a pure I/O serializer.
