Please note that the idea was to have some of the statistics NOT be
media resource specific. In particular:

* bytesReceived
* downloadTime, and
* networkWaitTime

are relevant to all resources that a Web page may embed. Thus, this
fits better with the general ResourceTiming2 spec.

What is relevant to only media is the DroppedFrames statistic and it
may make more sense to have that in the media element itself, if it is
the only metric that we're after for the video element.
