feat(php): 添加类定义管理和属性访问优化功能

- 实现 addClass 方法用于添加类定义到编译器
- 优化 hasNativeClass 和 getClassDef 方法使用 escapeClass 处理类名
- 更新 escapeClass 方法支持反斜杠替换为下划线并去除首尾反斜杠
- 重构 getPropertyIdentifier 方法简化属性标识符获取逻辑
- 新增 findNativeProperty 方法实现原生属性查找功能
- 添加对私有、受保护和公共属性的访问权限检查
- 支持继承链中属性的向上查找功能
- 为 get_class_vars 函数添加完整的测试用例覆盖
