feat(godot): 添加Godot游戏开发相关组件和系统

- 新增架构层支持，包括AbstractArchitecture和ArchitectureAnchorNode
- 实现拖拽功能组件AbstractDragDrop2DComponentBase和AbstractDragDropArea2DComponent
- 添加节点扩展方法类NodeExtensions，提供多种实用的节点操作方法
- 新增资源目录系统AbstractAssetCatalogSystem用于管理游戏资源
- 实现音频管理系统AbstractAudioManagerSystem支持背景音乐和音效播放
- 添加取消注册扩展方法UnRegisterExtension
- 创建GFramework.Game项目模块
- 重构项目结构，聚合核心模块并优化依赖引用
