cpuquiet: Runnable threads governor
[perf] The runnable threads governor only looks at the average number of
runnables in the system to make a decision when bringing cores
offline/online. First pass; tweaks thresholds and delays to reduce
decision latency to about ~50-70ms per core (from ~100-150ms per core)
