Connor O'Brien 8bea10e033 ANDROID: cpufreq: track per-task time in state
Add time in state data to task structs, and create
/proc/<pid>/time_in_state files to show how long each individual task
has run at each frequency.
Create a CONFIG_CPU_FREQ_TIMES option to enable/disable this tracking.

Bug: 72339335
Bug: 127641090
Test: Read /proc/<pid>/time_in_state
