This is preliminary work for/from #4220 (async `Layer::get_value_reconstruct_data`). There, we want to switch `Timeline::layers` to be a `tokio::sync::RwLock`. That will require the `TimelineWriter` to become async, because at times its functions need to lock `Timeline::layers` in order to freeze the open layer. While doing that, rustc complains that we're now holding `Timeline::write_lock` across await points (lock order is that `write_lock` must be acquired before `Timelines::layers`). So, we need to switch it over to an async primitive.
