[repaint-after-layout] Only repaint SVG root element when needed.

With Repaint-After-Layout we would repaint the SVG Root element a lot more
then needed. This ports the check for when to repaint the SVG Root element
into the LayoutRectRecorder to better match what the LayoutRepainting was doing
originally.

Remove style attribute from SVGElement.idl

This attribute is already present on Element.idl. This change avoids extra bindings code
being written.

Remove SkiaFontWin as it is no longer used

Remove the SkiaFontWin.cpp and SkiaFontWin.h files and all references
to them as the paintSkiaText method provided by SkiaFontWin.h is no
longer used now that the Uniscribe code path has been removed.
