El2.0 ios (#871)
* port ios winit el2.0 implementation to the new rust-windowing repo * unimplemented! => unreachable trailing comma in CFRunLoopTimerCallback * implement get_fullscreen * add iOS specific platform documentation. Add a TODO about how to possibly extend the iOS backend to work have methods callable from more than just the main thread * assert that window is only dropped from the main thread * assert_main_thread called from fewer places
