Update VP8 settings to avoid spending bitrate on static areas. PERF NOTE
This CL changes the threshold where we consider a block to be static and
of sufficient quality to not spend bits/CPU encoding it.
Perf note: This change may result in a minor degradation of PSNR/SSIM
and available send bitrate. CPU usage and bitrate sent should however
be greately reduced.
