sfx2::sidebar::ControllerFactory::CreateToolBoxController
only supports creating controllers using the uno factory,
or GenericToolbarController as a fallback. Given that we
already handle the uno factory case in
ToolBarManager::CreateControllers, all this complexity is
really just for creating GenericToolbarController with a
different ctor, which we can do locally as well.
