refactor(ast): 统一记录类型结构并移除成员访问操作符

Browse Source 
- 移除了枚举类型的独立结构定义，统一使用record结构
- 移除了成员访问操作符SCC_AST_OP_MEMBER_ACCESS和SCC_AST_OP_PTR_MEMBER_ACCESS
- 更新了for循环语句中init字段的类型从scc_ast_type_t*到scc_ast_node_t*
- 修改了声明初始化函数以支持统一的记录类型处理

fix(ast2ir): 完善二元表达式处理和for循环代码生成

- 重构了赋值操作符的处理逻辑，通过临时表达式实现复合赋值
- 添加了对for循环语句的完整IR代码生成功能
- 修复了if-else语句中错误的基本块跳转问题
- 改进了标识符未找到时的错误提示信息

chore: 清理代码和修复潜在问题

- 移除了未使用的自动标签生成功能
- 统一了IR基本块标签格式化输出
- 修复了机器码生成中的寄存器存储控制流问题
- 改进了词法分析器中十六进制数字的处理逻辑
