cc: Make layer updating optional in BeginMainFrame
If no-one has requested a layer update, either by calling
Proxy::SetNeedsUpdateLayers() or Proxy::SetNeedsCommit(), skip computing
the layer update in BeginMainFrame. This reduces the static overhead of
a BeginMainFrame/Commit operation when the layer tree doesn't change.
This change improves efficiency, for example, when a page has a
requestAnimationFrame callback which does not modify the DOM.
