Yicong-Huang opened a new pull request, #56948: URL: https://github.com/apache/spark/pull/56948
### What changes were proposed in this pull request? Remove `ArrowStreamAggPandasUDFSerializer` from `serializers.py`. This class is no longer used after SPARK-57676 refactored `SQL_GROUPED_AGG_PANDAS_ITER_UDF` (the last consumer) to use `ArrowStreamGroupSerializer` directly, following the earlier refactors of `SQL_GROUPED_AGG_PANDAS_UDF` (SPARK-56781) and `SQL_WINDOW_AGG_PANDAS_UDF` (SPARK-57381). ### Why are the changes needed? Dead code cleanup. Part of SPARK-55384 (Refactor PySpark Serializers). Mirrors the equivalent Arrow-side cleanup in SPARK-56349. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing tests. No behavior change. ### Was this patch authored or co-authored using generative AI tooling?
