Just keeping wasm-opt up to date.
I don't see anything in the [binaryen
changelog](https://github.com/WebAssembly/binaryen/blob/main/CHANGELOG.md)
that should affect substrate.
This release includes dwarf passes that were accidentally omitted from
previous versions of the wasm-opt crate. I suspect this will not affect
substrate as their omission hasn't been noticed until recently.
