Add simple version of activity masking.
This uses MB variance to change the RDO weight for mode decision and quantization. Activity is normalized against the average for the frame, which is currently tracked using feed-forward statistics. This could also be used to adjust the quantizer for the entire frame, but that requires more extensive rate control changes. This does not yet attempt to adapt the quantizer within the frame, but the signaling cost means that will likely only be useful at very high rates.
