refactor(php): 重构函数和方法定义解析逻辑

- 修改 parseFunctionDeclaration 方法参数类型，支持 Function_ 和 ClassMethod
- 简化函数定义创建流程，直接在构造函数中初始化 name 和 returnType
- 更新 parseParams 方法接受 FunctionDef 参数，避免使用全局变量
- 重命名格式化提示信息从 formatting 为 format
- 重构 FunctionDef 类添加构造函数并调整属性初始化
- 修改 MethodDef 类结构，使用 FunctionDef 对象替代单独的 returnType 属性
- 更新 Translator 中的方法调用以适配新的 MethodDef 结构
- 调整类方法解析流程以兼容新的数据结构
