  [Filters] Manage applying the SVGFilter using FilterTargetSwitcher

Reviewed by Simon Fraser.

FilterTargetSwitcher will be used to apply the SVGFilter. It will replace the
sourceImage of FilterData. GraphicsContext filters will be used if
FilterTargetSwitcher::create() decides to create FilterStyleTargetSwitcher.

Unlike the CSSFilter, the SVGFilter does not require clipping the drawingContext
before drawing since it draws the whole filtered image in one time.
