Summary [LBSE] Suppress LayoutRepainter inside SVG hidden/anonymous containers

Extend `RenderElement::checkForRepaintDuringLayout()` to return `false` when LBSE is enabled and the element either is an anonymous SVG container (e.g. the viewport container child of `RenderSVGRoot`) or is nested inside a `RenderSVGHiddenContainer`.
