[11.x] Improvements for the ServeCommand (add more loves & elevate DX)

[sethsandaru]

Hi guys,

As a person who really loves the php artisan serve and jumps into the development immediately, I'd like to add some improvements and hopefully, it would help other developers too

1. Print out a better request time, for requests that take less than 1 second, ~0s doesn't seem so helpful at all.
2. Show the request's route instead of "........."

Thanks all.
