Surface creation

On Android, surface creation should happen on the resume event of the window, and surface cleanup on the suspend event. A valid surface cannot be created beforehand. This means that, when using winit, sdl2, or anything similar, surface creation should happen in the resume handler, roughly like this:

// winit's `ApplicationHandler::resumed`:
fn resumed(&mut self, event_loop: &ActiveEventLoop) {
    let window = event_loop.create_window(Window::default_attributes()).unwrap();
    let surface = instance.create_surface(window).unwrap();
    // ...
}

Correspondingly, drop the Surface when the window is suspended.
