Add debug symbol generation for Release builds of PAGViewer and PAGExporter.

[CodeJhF]

为 PAGViewer 和 PAGExporter 的 Release 构建添加调试符号生成支持：

1. CMake 配置: 在 Release 模式下为 Clang 添加 -g 编译选项，为 MSVC 添加 /Zi 和 /DEBUG 链接选项
2. macOS dSYM 支持: 为 PAGViewer 和 PAGExporter 自动生成 dSYM 文件，支持 x86_64 和 arm64 架构的通用二进制文件
3. Windows PDB 支持: 为 Windows 平台生成并收集 PDB 调试符号文件
4. 符号文件管理: 调试符号文件与发布包分离，便于崩溃分析和调试

这些改进将显著提升线上问题的调试效率和准确性，同时保持 Release 模式的完整优化。
