WebAssemblyから関数渡しできないので，これ実装無理では．
WebAssembly内の関数名の取得も無理なので，自前で実装するにしてもコンパイラのレベルで細工が必要．

番号とかで関数を指定できても，C→WebAssemblyが難しい．

  IM3Function f;
  result = m3_FindFunction(&f, runtime, "_start");
  if (result)
  {
    wasm3_error_printer("m3_FindFunction", result);
  }

でできる可能性はあるが，これはあくまでエントリーポイントとなる関数指定
