Cleanup of unnecessary WebWidgetClient compositor methods

Cleanup of unnecessary WebWidgetClient compositor methods

There are several compositor-specific WebWidgetClient methods that are
unused by Blink and implemented by RenderWidget. These methods are only
used by RenderWidgetCompositor. Decouple the Blink dependency, making
these methods local to content/.

The WebWidgetClient methods will be removed in
https://codereview.chromium.org/1174273005.

Should that happen after calling the observers to be equivalent to before the
patch?
