Initialize SVGStaticStringLists with correct animated type.

Initialize SVGStaticStringLists with correct animated type.

Until now, SVGStaticStringLists were initialized with
AnimatedStringList animated type. This was the reason why SVG
test attributes - with SVGStaticStringList type - were considered
as valid animatable attributes and why we ran into a crash later.
This patch initializes SVGStaticStringLists with AnimatedUnknown
type to avoid any attempts to animate them later.
