Framework for LaunchBoost v2 and Frequency aggr during launch. 

Extending original launch boost to
benefit apps that take more than 2 secs
to finish launch.

This is improved in two different ways.
1) Frequency aggregation during launching a
large app.
(Ex: Templerun2 launch latency improves by 5 secs)

2) LaunchBoost v2 to set various sched params
or cpu sets during launch of a large app.

Both perflocks are a more light weight boost
without any cpu boosts and shows good benefit to
large app launch latencies.
(Ex: Games)

Also responds to user touch as one form to indicate
end of launch and stop boosts.
