What I had in mind was to have ApplyWebPreferencesInternal be a (private?)
method on RenderViewImpl, and keep an ApplyWebPreferences on RenderView, with
the same signature as the current one.
The reason is that we don't want to expose CompositorDependencies in the public
content API since it's an implementation detail.

Done.
