refactor(php): 重构PHP编译器函数声明解析和包装生成逻辑

- 修改parseFunctionDeclaration方法移除name参数，直接从节点获取函数名
- 修复错误消息中的变量引用，使用$v->name替代传入的$name参数
- 统一FunctionDef创建时的名称解析，使用parseIdentifier处理节点名称
- 更新parseFunctionDeclaration调用处，传递节点对象而非名称字符串
- 重命名genMethodWrapper为genWrapperFunctionArgs并重构参数处理逻辑
- 添加对方法和函数的不同参数处理逻辑，区分是否包含this_参数
- 重构genMethodWrapper方法以复用新的genWrapperFunctionArgs功能
- 在Constants.php中添加char关键字到保留字列表
