LibGUI: Add and use Window::center_on_screen()

Browse source 
Various applications were using the same slightly verbose code to center
themselves on the screen/desktop:

Gfx::IntRect window_rect { 0, 0, width, height };
window_rect.center_within(GUI::Desktop::the().rect());
window->set_rect(window_rect);

Which now becomes:

window->resize(width, height);
window->center_on_screen();
