Enables usage of dictionary columns as partition columns on write. Additionally resolves some partition-related follow ups from #8894 (@pitrou): - raise an error status [instead of aborting](https://github.com/apache/arrow/pull/8894/#discussion_r545219042) for overflowing maximum group count - handle dictionary index types [other than int32](https://github.com/apache/arrow/pull/8894/#discussion_r545215901) - don't build an unused null bitmap [in CountsToOffsets](https://github.com/apache/arrow/pull/8894/#discussion_r545212237) - improve docstrings for [MakeGroupings, ApplyGroupings](https://github.com/apache/arrow/pull/8894/#discussion_r545209568) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
