### What changes were proposed in this pull request? This PR consolidates `ArrowStreamAggArrowIterUDFSerializer` with `ArrowStreamAggArrowUDFSerializer`. ### Why are the changes needed? When the iterator API was added for Arrow grouped aggregation UDFs, a new `ArrowStreamAggArrowIterUDFSerializer` class was created. However, this class is nearly identical to `ArrowStreamAggArrowUDFSerializer`, differing only in whether batches are processed lazily (iterator mode) or all at once (regular mode). By consolidating these two classes, we reduce code duplication and maintain consistency with similar serializer consolidations. ### Does this PR introduce _any_ user-facing change? No, this is an internal refactoring that maintains backward compatibility. The API behavior remains the same from the user's perspective. ### How was this patch tested? Existing Tests ### Was this patch authored or co-authored using generative AI tooling? No -- This is an automated message from the Apache Git Service.
