Android Google马甲包处理

这是整理其他人的plugin代码，最后有亮点，耐心看下吧

plugins {    id 'com.android.application'    id 'org.jetbrains.kotlin.android'    id 'xml-class-guard'//    id 'AndResGuard'//    id 'com.bytedance.android.aabResGuard'//    id 'stringfog'    id 'android-junk-code'//    id 'kotlin-android-extensions'}

gradle文件增加以下代码

在人家的基础上

我优化了名字的随机性

androidJunkCode这个感觉意义不到，基于asm我自己定义了一版逻辑

这是我处理后的结果，插入了很多无用代码在每个方法上

 3、stringfog优化支持了buildConfig的字符混淆
