AI 143748: Fix issue #1743326 (More battery stats)

Browse Source 
Adds stats for:
  - Number of raw user events that have happened in the system.
  - Number of times user activity has been reported, dividied by UID and type of activity.
  - Duration of screen brightness levels in 4 buckets.
  - Per-UID tracking of who has turned on Wifi and how long we can attribute it being on because of them.
  BUG=1743326
