refactor(format): 移除SCF格式相关文件

移除了libs/format目录下的所有文件，包括：
- cbuild.toml构建配置文件
- include/scf.h头文件
- include/scf_impl.h实现头文件
- src/scf.c源文件
- tests/test_scf.c测试文件
- tests/test_scf_x64.c x64架构测试文件

这些文件包含了SCF（scc format）格式的完整实现，但现在不再需要。

feat(lexer): 添加布尔字面量数字生成函数

在lexer工具头文件中添加了两个内联函数用于生成布尔值的数字字面量：
- scc_lexer_gen_number_true: 将token类型设为整数字面量，值为"1"
- scc_lexer_gen_number_false: 将token类型设为整数字面量，值为"0"

refactor(lexer): 改进词法分析器错误处理

- 移除了多余的头文件包含
- 更新错误报告方式，使用SCC_ERROR宏替代LEX_ERROR，提供更准确的错误位置信息

refactor(pproc): 更新预处理器扩展器数据结构

- 将need_rescan字段类型从int改为cbool
- 添加need_parse_defined字段用于控制defined操作符解析
- 更新函数签名以支持defined操作符解析参数
