feat(compiler): 添加类常量获取支持并优化参数信息处理

- 在 CompilerBase.php 中添加对 Expr_ClassConstFetch 类型的支持
- 修改 getArgInfo 方法签名以接收 Node 参数并添加参数不存在时的错误处理
- 修复三元运算符解析逻辑以正确处理省略中间表达式的情况
- 将 null 常量映射从 nullptr 改为 php::null
- 扩展 hasVar 方法以支持更多变量类型包括静态属性和对象属性
- 添加 parseClassConstFetch 方法用于处理类常量获取表达式
- 在 gen_stub.php 中修复缺少可见性修饰符和参数类型的处理
- 跳过生成 ext_functions 条目当类名不存在时
- 在 Translator.php 中添加存根文件生成的状态检查和错误报告
