[LBSE] Prepare layer position, stacking and visibility handling for
non-layered SVG renderers
https://bugs.webkit.org/show_bug.cgi?id=317352
Reviewed by Rob Buis.
Teach the layer machinery about SVG renderers that have no layer of their own:
accumulate locationOffsetEquivalent() for non-layer SVG ancestors in
updateLayerPosition(), establish a stacking context for SVG-layer-aware
renderers, drop the anonymous-viewport-container computeHasVisibleContent()
special-case, relax the scrollable-area assert for an SVG document element,
guard
dirtyEnclosingLayerSVGChildrenIfNeeded() on isSVGLayer(), and preserve
RenderSVGImages container-relative location during layout.
This is a preparation for conditional SVG layer creation.
