Always use the WebFrameWidget when attaching the root graphics
layer or the compositor animation timeline in ChromeClientImpl.

Now that we always instantiate a WebFrameWidget for local
roots, we can remove the fallback code that goes directly
through WebView.

This change also fixes an issue where local roots were not
being passed to
ChromeClientImpl::attachCompositorAnimationTimeline which
caused the AnimationTimeline to be attached to the wrong
widget.
