:art: #1390 微信支付增加XML转换的快速模式，发送请求以及组装响应对象的时候不再依赖反射机制

* 增加XML的快速模式，发送请求以及组装响应对象的时候，不再依赖java的反射机制。
1：提升性能
2：可以通过 graalvm 生成native image.

本次完成：全部BaseWxPayRequest的改造，部分BaseWxPayResult子类的改造。

* clean code

* 标记 xmlDoc 为 transient 否则toString()方法中Gson可能会堆栈溢出

* 完成大多数BaseWxPayResult子类的改造。还有 notify.*Result下面留了两个TODO需要处理。

* toXML时遗漏了sign参数

* 使用dom4j简化了toXML，同时根据本版本构建native-image的demo已经提交： https://github.com/outersky/wx-micronaut-graal.git 供参考。

* 完成了最后两个Result的xml解析。
