test-wasm: Convert WebAssemblyModule::create() to ThrowCompletionOr

This exposed a missing exception check in parseWebAssemblyModule(),
which could throw but still return a normal completion (which currently
works as we check VM::exception() at the right point, but breaks when
moving everything to exceptions).
