新增 AppDomainDllLoader 和 DesignPluginEntry 类

在 AppDomainDllLoader.cs 文件中新增了 AppDomainDllLoader 类，用于处理 DLL 加载问题，解决依赖问题。
在 DesignPluginEntry.cs 文件中新增了 DesignPluginEntry 类，增加3D插件入口。
在 PluginEntry.cs 文件中，修改了 Version 属性的获取方式，并新增了对 AppDomainDllLoader.SetLaoder() 方法的调用。
在 AssemblyInfo.cs 文件中，更新了程序集的版本信息，将 AssemblyVersion、AssemblyFileVersion 和 AssemblyInformationalVersion 都更新为 1.0.0.6。
在 Sinvo.EplanHpD.Plugin.csproj 文件中，新增了对 HandyControl 库的引用，并添加了 AppDomainDllLoader.cs 和 DesignPluginEntry.cs 文件的编译项。
在 packages.config 文件中，新增了 HandyControl 库的包引用，版本为 3.2.0，目标框架为 net481。
