refactor(log): 统一日志系统并添加链接器实现

Browse Source 
- 为所有模块添加统一的 scc_*_log.h 日志头文件，删除旧的 lexer_log.h/c
- 将运行时日志从 scc_utils 迁移到 scc_core 目录，统一日志管理
- 在解析器表达式/语句/类型解析中添加 LOG_TRACE 调试日志
- 实现 SCCF 链接器 (sccf_linker) 支持多目标文件链接
- 重构 CLI 主程序 (main.c/config.c)，新增 cmd_log.h 调试支持
- 优化 x86 指令编码操作数对齐检查
- 修复预处理器的指令处理和宏展开逻辑
