[LBSE] Fix SVGImage container size propagation
https://bugs.webkit.org/show_bug.cgi?id=246034

Reviewed by Rob Buis.

Propagate container size in SVGImage also for RenderSVGRoot, not only LegacyRenderSVGRoot.
This requires to enable SVGImage to actually use LBSE for its documents, if the host document
has LBSE turned on.

This requires plumbing the 'layerBasedSVGEngineEnabled' flag from Settings (reachable via Document)
down to CachedImage / ImageObserver so that we can set the flag, if necessary, before constructing
the document from the network data. Otherwise SVGImage in LBSE will continue to use the legacy
SVG engine.

Update TestExpectations now that SVGImage uses LBSE as well.
