Fix the fetching of images in CF_DIB format in DisplayServerWindows::clipboard_get_image

Fix the fetching of images from windows clipboard, if they're in CF_DIB format (e. g. by taking screenshots).

Image::create_from_data was used with an instance of Image, but it's a static function, returning a new instance.
