Add CPU Scheduler Governors.

Browse source 
Add a new enumeration for cpu scheduler governors.
Adds a property to get the available governors as a map of
value to strings similar to how we expose GPU Power Profiles.
Adds another property to get and set the current governor which
is applied to all cpus when set.
