Fix crash when no power_profile is specified
Always connected devices don't have power_profiles,
so handle the case where the default cpu speed count of
1 is used on a device with more cpu speeds.

BatteryStats: Better big-little CPU accounting
Generalize cpu clusters so we can measure frequency
and power usage across heterogeneous cpu clusters.
This also brings back reading of cpu-times for power calculation.

Parse uid_cputime proc file
Instead of using the ProcessCpuTracker as the source of truth, we
periodically poll the new uid_cputime kernel module for stats
on all UID cpu time.
TODO: Need to tell the kernel when to stop tracking UIDs (aka on package
uninstall).
