Subject : scheduler: Throttle timers in out-of-view frames
Author : skyostil
Commit description:
Throttle timer tasks to 1 Hz in out-of-view or invisible frames. This
reduces the power consumption and performance impact of these tasks,
which are not likely having any visible effect on the page anyway.

Started a trace for the smoothness.top_25_smooth regression: https://codereview.chromium.org/2305943003
(I think we can ignore the sync scroll regression since that test is pretty artificial. The fact that it regressed there too might help to debug this other one however)
