[LBSE] Use weak references in SVGPaintOrderLayerItem to avoid keep-alive of
dead renderers
https://bugs.webkit.org/show_bug.cgi?id=313784
Reviewed by Rob Buis.
SVGPaintOrderLayerItem caches direct or descendant RenderElement / RenderLayer
pointers as part of RenderLayer::m_svgData->childrenInDOMOrder. The previous
CheckedPtr<RenderElement> / CheckedPtr<RenderLayer> fields had keep-alive
semantics for both targets. The cache unintentionally extended renderer/layer
lifetime - avoid that.
Switch the fields to SingleThreadWeakPtr<RenderElement> /
InlineWeakPtr<RenderLayer>.
