Do we need to replace the current `-mattr=+bulk-memory` with `+bulk-memory-opt` in all the tests where it doesn't matter? I am not strongly opinionated whether we should or should not add the non-Wasm-proposal features, but I'm not sure whether it should be used in all the tests instead of the old features.
