Update the walrus dependency (#2125)
This commit updates the `walrus` crate used in `wasm-bindgen`. The major
change here is how `walrus` handles element segments, exposing segments
rather than trying to keep a contiugous array of all the elements and
doing the splitting itself. That means that we need to do mroe logic
here in `wasm-bindgen` to juggle indices, segments, etc.
