feat(lexer): 添加SCC语言扩展关键字支持并重构标准定义
- 将SCC_CEXT_ASM重命名为SCC_CEXT_SCC以更好地反映扩展类型 - 为asm关键字添加SCC_CEXT_SCC标准标识 - 新增atomic、auto、bool、complex四个关键字及其对应的token类型 - 所有新关键字都标记为SCC_CEXT_SCC扩展标准 fix(lexer): 修复数字字面量解析中的类型不匹配问题 - 将token->value.n更正为token->value.u以正确存储解析结果 - 统一了词法分析器中数值解析的字段访问 refactor(log): 重构日志系统API设计并增强功能 - 将日志处理器接口从void返回改为int返回类型 - 新增函数名记录功能，通过__func__宏获取当前函数名 - 引入可变参数支持，允许格式化字符串传递 - 重构内部宏实现，使用SCC_LOG_IMPL统一处理逻辑 - 改进缓冲区管理，优化日志消息格式化流程 - 重命名头文件保护宏从__SCC_LOG_H__到__SCC_LOG_IMPL_H__ - 替换snprintf为vsnprintf以支持可变参数处理 - 更新断言宏实现，提供更清晰的错误信息格式
