Don't load CSS resources for non-rendered elements.

The current situation was that we triggered loading of all resources,
like background-images, for an element we computed style for. Instead,
align with Firefox and Safari to skip fetching for:

* display:none elements
* elements in display:none subtrees
* display:contents elements
* elements outside the flat tree

Note that we still trigger fetches for visibility:hidden, which is in
line with what Firefox and Safari does.

Also removed an unnecessary StyleResolver::LoadPendingResources wrapper.
