feat(compiler): 添加对 Match 表达式和枚举的支持

- 在 CompilerBase 中添加了对 Expr_Match 节点的解析支持
- 修改 parseTernary 方法参数类型为 Node\Expr\Ternary
- 添加了 parseMatch 方法用于处理 Match 表达式
- 在 Preprocessor 中添加对 Stmt_Enum 和 Stmt_EnumCase 的预处理支持
- 扩展 prepareClass 方法以支持枚举类型的处理
- 在 Translator 中添加对 Stmt_Enum 的翻译支持
- 修改 parseClass 方法以正确处理枚举定义
- 添加测试文件 closure_016.phpt 和 closure_017.phpt 验证闭包功能
- 添加枚举示例文件 enum1.php 展示枚举用法
