Revert of telemetry: Clean up SurfaceFlinger statistics

Revert of telemetry: Clean up SurfaceFlinger statistics (patchset #8 id:140001 of https://codereview.chromium.org/765773004/)

Reason for revert:
Perf sheriff here, speculatively reverting due to crbug.com/442752, it shows up in many blamelists (but not all as the test wasn't running due to another bug). Sorry if unrelated.

Original issue's description:
> PERF-SHERIFFS: This patch will change all smoothness and SurfaceFlinger metrics on Android. Some metrics may go up or down significantly, with the new values being more accurate.
>
> This patch cleans up the integration of SurfaceFlinger statistics by pulling the
> raw timestamps into the timeline and calculating all metrics in
> SmoothnessMetric. This approach also improves the metrics, because the
> timeline ranges can now be properly bounded (no more percentiles!) and the
> existing smoothness metrics can also use the more accurate SurfaceFlinger
> timestamps.
