    [FLINK-9087] [runtime] close the BufferConsumer in RecordWriter.broad…

    ## What is the purpose of the change
    
    BufferConsumer  is Closeable, we'd better close it at last, 
    
    
    ## Brief change log
    
    RecordWriter.broadcastEvent()  is called in StreamTask., RecordWriterOutput ,IterationIntermediateTask
and IterationHeadTaskbroadcastEvent, also notice that no one make use of the BufferConsumer
returned by broadcastEvent(), so i think the better way to close the return value in RecordWriter.
change  the method signature from   BufferConsumer to void, and close the BufferConsumer
in the end.
