      Investigate possibilities to improve performance of mfwrapper.

      It was noticed that using TopoEdit (tool to build Media Foundation topologies) was able to play 4k H.265 media file with 50-60% CPU utilization, but when playing via JavaFX Media CPU utilization is 75-90%. When memcpy() of raw frames was disabled CPU utilization under JavaFX Media dropped to 60-70% including dual color conversion introduced with JDK-8336277. I think with JDK-8337686 and avoiding memcpy() of raw frames performance similar to TopoEdit can be achieved.
