Android: Consolidate and simplify VSync logic

This moves handling of VSync over to WindowAndroid.
It can have one client to receive vsync signals 
for the main browser-side scheduling logic.
It also forwards the vsync to the WindowAndroidObservers,
i.e. RenderWidgetHostView where it's used for sending
BeginFrame signals to the renderer.

This prepares for consolidating the scheduling logic
in a single place upstream.

Which will then further allow us to use the
cc scheduler (with SingleThreadProxy) and
unblock the landing of https://codereview.chromium.org/134623005/.
