Replace wasm-opt in bindings dep with local version

[wulfraem]

Description of change

PR removes outdated wasm-opt installed via NPM, and add the requirement to have wasm-opt installed locally, which allows using newer versions, that are compatible with the latest Rust toolchain versions.

This updates the wasm-opt used in the build process to its latest version.

In related projects, we had an error related to newer Rust versions and outdated wasm-opt version ([parse exception: invalid code after misc prefix: 17 (at ...)]) thrown during build, which was fixed by the same changes. The error does not seem to be thrown at the moment (checked in CI), but possibly will have been with future changes in the code. Using an up-to-date wasm-opt version should prevent this.
