HarmonyOS Napi Arraybuffer无法创建

在napi中创建Arraybuffer，可参考链接：

https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/napi/napi-guidelines.md#%E9%AB%98%E6%80%A7%E8%83%BD%E6%95%B0%E7%BB%84

示例代码如下：

char const * str = “hello world”;
size_t charLength = strlen(str);
napi_value output_buffer;
void *output_ptr = (void *)str;

napi_create_arraybuffer(env, charLength, &output_ptr, &output_buffer);
uint8_t *output_bytes = (uint8_t *)(output_ptr);

uint8_t *input_bytes = (uint8_t *)str;
for (int i = 0; i < charLength; i++) {
  output_bytes[i] = (uint8_t)(input_bytes[i]);
}

return output_buffer;
