This addresses ENG-10270.
Changes here:
- Upgrade everything to Rust 1.85.
- In order to address ENG-9892:
- We need to bump our Webpack version (see here).
- We also need to use a higher version of binaryen than the one we're getting from apt-get, so I introduced a script to download a later version binary.
- Finally, we need to pass --reference-types to wasm-pack.
