Add LogBuffer that passively tracks touch handling in the shade
Logs will passively observe calls to ViewGroup.onInterceptTouchEvent
for all top level ViewGroups for each major section of the shade,
e.g. QS, NSSL, Keyguard, Bouncer. Additionally, it will track
touches on Views near the top of the shade's hierarchy like
scrims and the long press detector.
