LibWeb: Store the SVG <use> element's referenced ID as a FlyString

Browse source 
We currently store a StringView into the DeprecatedString provided to
SVGUseElement::attribute_changed. This is a temporary string created by
String::to_deprecated_string, so this StringView is always a dangling
pointer.

Instead, since this string value is an ID and is primarily used as a
FlyString, store it as a FlyString from the get-go.
