[图形工具更新]: 新增多页面跳转功能并优化图像查看体验

- **新增多页面跳转功能**: 在图像查看器中添加"跳转到多页"按钮，支持从单张图像查看快速跳转到多图像文件查看器
- **统一应用信息管理**: 移除独立的appinfo.hpp文件，将版本信息等统一整合到utils/appdata.hpp中
- **增强图像格式支持**: 扩展支持的文件格式，新增对ICO格式的支持
- **优化拖拽体验**: 为OpenGL和RHI视图添加拖拽打开图像文件的功能
- **改进缩放计算**: 修正缩放因子计算逻辑，考虑设备像素比确保显示精度
- **修复图像加载**: 优化空路径处理和图像缓存机制，提升稳定性
- **代码结构优化**: 调整界面布局和信号槽连接，提高代码可维护性
- **多视图协同**: 实现图像查看器、OpenGL查看器和Vulkan查看器之间的页面跳转联动
