desktop: Take ownership of `EventLoop` on `App::run`
Change `App::event_loop` to an `Option` that will be taken on `App::run` so that `App::run` can continue to call methods on `self` later. This is a little awkward, and better might be to remove `App::new` and make `App:run` return `Result<!, Error>,` but `!` types are experimental.
