### What changes were proposed in this pull request? This change adds MapType support for PySpark with Arrow, if using pyarrow >= 2.0.0. ### Why are the changes needed? MapType was previous unsupported with Arrow. ### Does this PR introduce _any_ user-facing change? User can now enable MapType for `createDataFrame()`, `toPandas()` with Arrow optimization, and with Pandas UDFs. ### How was this patch tested? Added new PySpark tests for createDataFrame(), toPandas() and Scalar Pandas UDFs. Closes #30393 from BryanCutler/arrow-add-MapType-SPARK-24554.
