Project: Spark
Issue Type: Sub-task

After all non-grouped Pandas eval types (SQL_SCALAR_PANDAS_UDF,
SQL_SCALAR_PANDAS_ITER_UDF, SQL_MAP_PANDAS_ITER_UDF) were refactored to use
ArrowStreamSerializer with ArrowBatchTransformer, and the last subclass
ApplyInPandasWithStateSerializer was removed in SPARK-58243,
ArrowStreamPandasUDFSerializer is now dead code with no instantiation sites.
Remove the class.
