GeWuYou 78af119f38 feat(generator): 添加上下文感知注入源码生成器
- 移除ContextAwareServiceExtensions中GetService/GetSystem/GetModel/GetUtility方法的可空返回值
- 添加ContextGetGenerator源码生成器,支持通过特性自动生成上下文注入代码
- 新增GetService/GetServices/GetSystem/GetSystems/GetModel/GetModels/GetUtility/GetUtilities/GetAll特性
- 添加ContextGetDiagnostics提供注入相关的编译时诊断检查
- 实现INamedTypeSymbol扩展方法AreAllDeclarationsPartial用于检查partial类声明
- 添加ITypeSymbol扩展方法IsAssignableTo用于类型兼容性判断
- 创建FieldCandidateInfo和TypeCandidateInfo记录类型用于存储生成器候选信息
- 添加IsExternalInit内部类型支持低版本.NET框架的init-only setter功能
- 更新AnalyzerReleases.Unshipped.md添加新的诊断规则条目
- 创建完整的单元测试验证生成器功能和各种边界情况
