Simplify InputRouter event filtering

The path that any given WebInputEvent takes through the RenderWidgetHost,
through the InputRouter and on to the renderer, is too complex.  Simplify
how events are routed, moving OverscrollController event dispatch code
into the router, removing all InputRouterClient::OnFooEvent callbacks, and
unifying how acks are processed synchronously from either being filtered
or consumed by the OverscrollController.
