<h3>Log Message</h3>
<pre>Simplify jettisoning of style resolvers on memory pressure.
<https://webkit.org/b/129644>
Now that we have Document::allDocuments(), we can jettison all the
style resolvers by walking the set of live documents and calling
clearStyleResolver() on each one, instead of having a function on
Page that walks the frame tree of every living page, etc.
