SurfaceFlinger TimeStats Metrics

Add timestats metrics for SurfaceFlinger. Keep track of global metrics
like total frames, missed frames, frames fellback to client
compositions, etc, as well as layer timing metrics like the delta
combination of postTime, desiredPresentTime, acqureTime, latchTime,
presentTime, etc. This metric is aimed at GMScore.

Test: dumpsys SurfaceFlinger --timestats [go/sf-timestats for more args]
