[FLINK-5157] [streaming] Extend AllWindow function metadata
This PR aims to extend AllWindow function metadata similarly to [FLINK-4997
](https://github.com/apache/flink/pull/2756).
Briefly, ProcessAllWindowFunction supporting window context metadata has
been introduced and AllWindowedStream apply/fold/reduce methods have been
overloaded in order to support this new function in both Scala and Java.
Moreover, new InternalWindowFunction sub-classes have been added for
internally handling ProcessAllWindowFunction-s.
