添加一个选项来控制是否执行 debugPrintRoute

(Optional) More detail description for this PR(en: English/zh: Chinese).

en: Added an option to control whether to print the route's log when it starts running, the default is to print. If panic occurs when there are many routes, because there is a lot of routing startup information, panic cannot be seen intuitively. Adding this option can avoid such a situation.

zh(optional): 新增了一个可选项来控制是否在开始运行时打印路由的日志，默认为打印。在路由较多时若发生panic，由于有大量的路由启动信息，因此不能直观的看到panic，增加此可选项后可避免此类情况出现。
