feat(grub-theme): 优化并新增Deepin grub主题支持

- 新增 adjustThemeNormalV25 处理函数，替代旧版本普通主题调整逻辑
- 重构调整启动菜单逻辑，简化 adjustBootMenu 函数，支持不同分辨率下的配置
- 在 Theme 结构体中添加 FindComponentByType 方法，便于根据类型查找组件
- 引入并使用 deepin-v20 主题数据，重命名相关资源文件路径
- 更新 deepin 主题的 theme.txt.tpl 模板，提高启动菜单和标签文字的配置灵活性
- 调整主题背景图片处理逻辑，支持保存背景及主题内背景图
- 测试代码中调用调整普通主题的函数改为新版本接口调用
- 优化字体和界面元素的样式及位置，提升视觉效果和一致性
