[aw] Support library glue for WebViewRendererClient

This exposes a support library feature allowing applications to set a
WebViewRendererClient object upon which renderer related callbacks are
received. Specifically, these callbacks are:

onRendererUnresponsive(renderer) - called when the renderer associated
    with a webview does not ack an input event, or a navigation does
    not commit within 5 seconds. The callback will continue to be
    called at 5 second intervals until the renderer is killed or the
    unresponsiveness resolves. |renderer| may be null if webview is
    operating in single process mode.

onRendererResponsive(renderer) - called once when an unresponsive
    renderer becomes responsive again.
