refactor(editor): 重构 Editor 使用 Engine 的 Component/Scene 系统

- Editor CMakeLists.txt 链接 XCEngine 库
- 删除 editor/src/Core/GameObject.h (简化版)
- SelectionManager 使用 Engine::Components::GameObject*
- SceneManager 使用 Engine::Scene
- HierarchyPanel 使用 Engine GameObject API
- InspectorPanel 使用 Engine TransformComponent

注意: Engine RHI Shader 接口有编译错误需要修复
