[root-scroller] Fix crash when considering plugin

Root scroller shouldn't consider plugins. However, the current method of
getting the scrollable area would check for a local frame and try to
convert its view to a LocalFrameView. In the case of a plugin, the
ContentFrame()->IsLocalFrame may return true but the EmbededContentView
is a PluginView rather than a LocalFrameView.

This CL cleans up these checks by looking exclusively at the
EmbeddedContentView since that's all we care about.
