feat(php): 实现魔术方法 __get、__set、__isset、__unset 的编译支持

- 修改 parseAssignPropertyFetch 方法，添加 literal 参数到 identifierToStr 调用
- 在条件判断中增加对 nativeProperty 属性的检查，区分原生属性和魔术方法调用
- 更新 parseUnset 方法中的属性名解析逻辑，统一使用 identifierToStr 并添加 literal 参数
- 重构 getPropertyIdentifier 方法参数列表，增加 expr 参数并设置 nativeProperty 属性
- 移除类属性不存在时的致命错误抛出，允许魔术方法处理未知属性访问
- 添加完整的魔术方法测试用例，覆盖 __get/__set/__isset/__unset 的基本功能
