Demarshals a value from a string.
Unlike gtk.builder.Builder.valueFromString, this function takes a gobject.types.TYPE_FLAG_RESERVED_ID_BIT instead of gobject.param_spec.ParamSpec.
Calls gobject.value.Value.init_ on the value argument, so it need not be initialised beforehand.
Upon errors false will be returned and error will be assigned a glib.error.ErrorG from the GTK_BUILDER_ERROR domain.
