[M144] media: Report multi-GPU histograms when MediaFoundation playback starts

Original change's description:
> media: Report multi-GPU histograms when MediaFoundation playback starts
> 
> - Report multi-GPU UMAs only once when the virtual video window size is
> the correct one (the output rect is larger than default size) since the
> window handle is required to determine where the video is displayed.
> - These histograms are required for further investigation on the high
> volume of "hardware-context-reset" cases with PlayReady SL3000 on
> Chrome Windows.
> 
> Tests:
> - Manually verified the histograms only reported once.
> - See the histogram example (tested 4 playbacks):
> http://shortn/_jDZxSVXsZH
