Implement RTCOutboundRtpStreamStats.totalEncodedBytesTarget.

This is a standardized metric:
https://w3c.github.io/webrtc-stats/#dom-rtcoutboundrtpstreamstats-totalencodedbytestarget

We estimate the target frame size in bytes from the current encoder
target bitrate and encoder framerate.

We would expect that the average bytes produced by the encoder would
over time match the average target, which is calculated by polling
getStats() twice and dividing the delta totalEncodedBytesTarget with
the delta framesEncoded. This is meant to make googTargetEncBitrate
obsolete.
