Move LayoutSVGResourceContainer registration to SVGTreeScopeResources

Move LayoutSVGResourceContainer registration to SVGTreeScopeResources

Move LayoutSVGResourceContainer::registerResource to
SVGTreeScopeResources, renaming it to updateResource while getting rid
of addResource (since it's only called from updateResource.)
Simplify the interaction with the m_pendingResources set a bit, to
eliminate a hash-lookup in certain code-paths.
