Create a new stateful action

• Before:

  Example:

  let actions = gio::SimpleActionGroup::new();
  
  let is_dark_mode = false;
  let action = gio::SimpleAction::new_stateful("dark-mode", None, &is_dark_mode.to_variant());
  action.connect_activate(move |action, _| {
      let state = action.state().unwrap();
      let action_state: bool = state.get().unwrap();
      let is_dark_mode = !action_state;
      action.set_state(&is_dark_mode.to_variant());
  });
  actions.add_action(&action);

• After:

  Example:

  let actions = gio::SimpleActionGroup::new();
  let is_dark_mode = false;
  stateful_action!(actions, "dark-mode", is_dark_mode, move |action, _| {
      let state = action.state().unwrap();
      let action_state: bool = state.get().unwrap();
      let is_dark_mode = !action_state;
      action.set_state(&is_dark_mode.to_variant());
  
      // Store the state using gsettings for example
  });
