Make requesting a CompositorFrameSink in the renderer async

If Chrome is running in mus, it will request a CompositorFrameSink from
Mus. That request is async. Currently RenderWidgetCompositor expects to
be able to synchronously request a CompositorFrameSink but LayerTreeHost
doesn't need this requirement. This CL makes the request for
CompositorFrameSinks asynchronous from RenderWidgetCompositor. There
is no change in functionality in this CL.
