### What changes were proposed in this pull request? Implement `DataFrame.mapInPandas` and enable parity tests to vanilla PySpark. A proto message `FrameMap` is intorudced for `mapInPandas` and `mapInArrow`(to implement next). ### Why are the changes needed? To reach parity with vanilla PySpark. ### Does this PR introduce _any_ user-facing change? Yes. `DataFrame.mapInPandas` is supported. An example is as shown below. ```py >>> df = spark.range(2) >>> def filter_func(iterator): ... for pdf in iterator: ... yield pdf[pdf.id == 1] ... >>> df.mapInPandas(filter_func, df.schema) DataFrame[id: bigint] >>> df.mapInPandas(filter_func, df.schema).show() +---+ | id| +---+ | 1| +---+ ``` ### How was this patch tested? Unit tests. Closes #40104 from xinrong-meng/mapInPandas. Lead-authored-by: Xinrong Meng <xinrong@apache.org>] Co-authored-by: Xinrong Meng <xinrong@apache.org> Signed-off-by: Xinrong Meng <xinrong@apache.org> (cherry picked from commit 9abccad) Signed-off-by: Xinrong Meng <xinrong@apache.org>
