feat(argparse): 添加枚举类型选项支持

Browse Source 
添加了对命令行参数枚举类型的支持，允许用户从预定义的选项中进行选择，
并在解析时进行验证。同时修复了空值检查问题。

refactor(mir): 重构pass管理系统

将原有的pass管理器系统简化为直接的pass执行函数，移除了复杂的
依赖管理和流水线构建机制，使系统更加简洁明了。

chore(ir): 添加Windows x64 ABI实现

实现了Windows x64平台的ABI约定，包括参数传递、寄存器使用和
栈帧布局的处理逻辑。

feat(config): 统一编译阶段控制配置

将多个独立的布尔类型编译阶段控制改为统一的枚举类型，便于
管理和扩展新的编译阶段。
