feat(ir2mcode): 实现AMD64代码生成器支持控制流和函数调用

- 实现了条件分支、无条件跳转和函数调用的机器码生成
- 添加了跳转目标地址回填机制,处理条件分支和跳转指令的偏移量
- 改进了寄存器分配逻辑,支持函数调用返回值的处理
- 重构了位置解析函数,从返回指针改为传入引用参数

fix(ast2ir): 移除无用的注释代码

- 删除了关于一元操作符映射的注释代码

test: 更新测试框架和测试用例

- 修改测试框架以支持新的可执行文件输出格式
- 添加了条件分支、循环和函数调用的测试用例
- 使用TOML配置文件管理期望的返回值
- 替换标准库头文件为自定义头文件以减少依赖
