Remove applyStatefulResource interface from SVGClipPainter

applyClippingToContext is equally "stateful", so the two entrypoints

Fold applyClippingToContext into applyStatefulResource and then rename
it to prepareEffect (to match mask and filter). Similarly rename
postApplyStatefulResource to finishEffect.
