Use SVGResources in SVGLayoutTreeAsText writeResources
As the FIXME suggests, this should better reflect the actual state of
the resources resolution by including the cycle-solving step.
Some tests (recursive-clip/mask, clip-path-recursive-call-by-child)
needs to be updated to reflect the change to actually show cycles
having been broken. The rests of the tests are updated to reflect
that LayoutSVGInlineText can't have resources.
