Subject: feat: add uv_loop watcher_queue code
Electron's Node Integration works by listening to Node's backend file descriptor in a separate thread; when an event is ready the backend file descriptor will trigger a new event for it, and the main thread will then iterate the libuv loop. For certain operations (ex. adding a timeout task) the backend file descriptor isn't informed, & as a result the main thread doesn't know it needs to iterate the libuv loop so the timeout task will never execute until something else trigger a new event. This commit should be removed when https://github.com/libuv/libuv/pull/1921 is merged
