Johannes Kron e76b3abf61 Add per frame decode time histograms for 4k/HD and VP9/H264
Add new histograms
WebRTC.Video.DecodeTimePerFrameInMs.[codec].[resolution].[decoder]
These histograms are more explicit than the existing histogram
WebRTC.VideoDecodTimeMs, since they allow to see performance per
codec/resolution/decoder and also contain per frame statistics instead
of an average decode time.

There's a killswitch, WebRTC-DecodeTimeHistogramsKillSwitch, that can be
used to disable the histograms.
