`WebAssemblyDebugValueManager` does not currently handle `DBG_VALUE_LIST`, which is a recent addition to LLVM. We tried to nullify them within the constructor of `WebAssemblyDebugValueManager` in D102589, but it made the class error-prone to use because it deletes instructions within the constructor and thus invalidates existing iterators within the BB, so the user of the class should take special care not to use invalidated iterators. This actually caused a bug in ExplicitLocals pass. Instead of trying to fix ExplicitLocals pass to make the iterator usage correct, which is possible but error-prone, this adds NullifyDebugValueLists pass that nullifies all `DBG_VALUE_LIST` instructions before we run WebAssembly specific passes in the backend. We can remove this pass after we implement handlers for `DBG_VALUE_LIST`s in `WebAssemblyDebugValueManager` and elsewhere. Fixes https://github.com/emscripten-core/emscripten/issues/14255.
