feat: add dock library and refactor dock plugin management

1. Added new libdde-shell-dock library to provide dock item interface
2. Created DAppletDock abstract base class for dock plugins with
dockItemInfo() and setVisible() methods
3. Refactored dock plugin management to use new library instead of
hardcoded plugin IDs
4. Updated build system to include new library and development packages
5. Modified multitaskview plugin to inherit from DAppletDock instead
of DApplet
6. Added dockVersion metadata field to identify dock-compatible plugins
7. Fixed installation paths for header files and libraries in Debian
packaging

Log: Improved dock plugin architecture with standardized interface

Influence:
1. Test dock plugin visibility management through settings
2. Verify multitaskview plugin still works correctly
3. Check that tray functionality remains unchanged
4. Test building and installation of new libdde-shell-dock packages
5. Verify backward compatibility with existing dock plugins
6. Test dock item information retrieval through D-Bus interface

feat: 新增Dock库并重构Dock插件管理

1. 新增libdde-shell-dock库，提供Dock项目接口
2. 创建DAppletDock抽象基类，包含dockItemInfo()和setVisible()方法
3. 重构Dock插件管理，使用新库替代硬编码的插件ID
4. 更新构建系统以包含新库和开发包
5. 修改multitaskview插件继承自DAppletDock而非DApplet
6. 新增dockVersion元数据字段以识别Dock兼容插件
7. 修复Debian打包中头文件和库的安装路径

Log: 改进Dock插件架构，提供标准化接口

Influence:
1. 测试通过设置管理Dock插件可见性
2. 验证multitaskview插件仍正常工作
3. 检查托盘功能是否保持不变
4. 测试新建libdde-shell-dock包的构建和安装
5. 验证与现有Dock插件的向后兼容性
6. 测试通过D-Bus接口获取Dock项目信息
