Elide the explicit any namespace prefix when lacking default namespace.
Once again it seems we don't need to preserve the original prefix name,
and this lets to_css serialize to the shortest form when there is no
default namespace and the *| prefix is used.
Selectors § 6.1.1 says:
Element type selectors that have no namespace component (no namespace
separator) represent elements without regard to the element's namespace
(equivalent to "*|") unless a default namespace has been declared for
namespaced selectors (e.g. in CSS, in the style sheet). If a default
namespace has been declared, such selectors will represent only elements
in the default namespace.
Then if there is no default namespace, *| (which we write as
QNamePrefix::ExplicitAnyNamespace) is equivalent to what we write as
QNamePrefix::ImplicitAnyNamespace; the latter has a shorter
serialization, so we should use that.
