LibWeb: Port CSSNamespaceRule to FlyString

Browse source 
This removes a performance problem where we'd convert the style sheet's
default namespace from DeprecatedFlyString to FlyString once per rule
during selector matching.

The conversion now happens once, during CSS parse. It should eventually
be removed from there as well, but one step at a time. :^)
