        Update expected results for some filters tests, now that their bounding box is correctly dumped.

        Move unit resolving for all resources to rendering/

        Reviewed by Andreas Kling.

        Remove maskBoundingBox()/filterBoundingBox(), to avoid doing length resolution in svg/.
        RenderSVGResource* now uses SVGLengthContext::resolveRectangle, to do this while laying out.

        Move linear gradient start/end point, radial gradient focal/center point, radius calculations into
        their RenderSVGResource classes, cleanup code a bit.

        Convert filters to use SVGLengthContext. Fix DRT dumps for filters, while I'm at it, to give
        meaningful values, when objectBoundingBox is used as primitive units, when applying to <text>/<tspan>s.

        Several tests results need rebaselines on all platforms.
