[FLINK-3578] Support RichFunctions for Scala Window Function and AllWindowFunction
This adds support RichFunctions for Scala Window Function and AllWindowFunction.
RichFunction method calls (`open()`, `close()`, `RuntimeContext`) are properly forwarded.
This also consolidates the various wrapper classes for fold() and reduce() functions.
