Update wasm-opt to 0.116 (#1995)
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.
