LibGUI: Add helper for constructing new TabWidget tabs

Browse source 
This patch adds the following convenience helper:

    auto tab_widget = GUI::TabWidget::construct();
    auto my_widget = tab_widget->add_tab<GUI::Widget>("My tab", ...);

The above is equivalent to:

    auto tab_widget = GUI::TabWidget::construct();
    auto my_widget = GUI::Widget::construct(...);
    tab_widget->add_widget("My tab", my_widget);
