[AUDIT 4.0] Evaluate new tunables for Python UDFs

[mythrocks]

We should evaluate whether the batch-size, buffer-size tunables introduced as part of SPARK-50752 have any bearing on spark-rapids's support for Python UDFs.

It doesn't appear that this change affects the code here. These might turn out to be knobs that we might use to tune things on our end. This task has been raised out of an abundance of caution.

The configs in question are:

1. spark.sql.execution.python.udf.maxRecordsPerBatch
2. spark.sql.execution.python.udf.buffer.size
