Abort the SVG filter content recording if the FilterData was dropped

Abort the SVG filter content recording if the FilterData was dropped

In the (rare) case of a recording being started and the FilterData
structure being yanked away (and destroyed) from under
SVGFilterPainter's feet, we need to put the PaintController in a
consistent state before destroying it.
Add a new method SVGFilterRecordingContext::Abort() and call that when
SVGFilterPainter::FinishEffect encounters a null FilterData for the
LayoutObject.
