    cssvalue: Add _gtk_css_initial_value_get()
    
    ... so we don't bump a refcount whenever we get the initial singleton.
    
    We want to use this function instead of
    _gtk_css_style_property_get_initial_value() everywhere where we compute
    values, because some initial values may depend on settings soon.
