cc: Emulate BeginFrame in OutputSurfaces that don't support it natively

Relanding again. This time, the proactive SetNeedsBeginFrame is
broken out explicitly with logic to workaround crbug 249806 and
to avoid expensive redraws with the synchronous renderer.

This includes two small fixes for the original version of this
patch that broke software compositing and WebView.

This will allow us to avoid having two different code paths
in the Scheduler. It also allows us to more easily remove the
VSyncTimeSource and FrameRateController from the Scheduler.

This patch instantiates the FrameRateController inside of
OutputSurface for now, but the FrameRateController could be
removed in future patches.
