[PR] [SPARK-56860][PYTHON] Remove unused CogroupArrowUDFSerializer [spark]
Yicong-Huang opened a new pull request, #55868:
URL: https://github.com/apache/spark/pull/55868
### What changes were proposed in this pull request?
Delete `CogroupArrowUDFSerializer` from `python/pyspark/sql/pandas/serializers.py`.
### Why are the changes needed?
`CogroupArrowUDFSerializer` is no longer used after SPARK-56312 refactored `SQL_COGROUPED_MAP_ARROW_UDF` to use `ArrowStreamCoGroupSerializer` directly. This class can be safely deleted.
Part of SPARK-55384.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Existing tests: `pyspark.sql.tests.arrow.test_arrow_cogrouped_map`.
