[FLINK-5066] Prevent LocalInputChannel#getNextBuffer from de-serialising
all events when looking for EndOfPartitionEvent only
LocalInputChannel#getNextBuffer de-serialises all incoming events on the
lookout for an EndOfPartitionEvent.
Instead, add EventSerializer.isEvent so that LocalInputChannel can peak
into event buffers without de-serialising the whole event, we could save some
resources. This is a generic isEvent implementation for any event that
fromSerializedEvent currently supports. Alternatively, a specialised method
could be implemented looking for EndOfPartitionEvent only, if desired.
