config_tools: refine virtio in launch script

Browse Source 
1. for virtio console, reference to the document
https://projectacrn.github.io/latest/developer-guides/hld/virtio-console.html,
the generated launch script will look like this:
`virtio-console,[@]stdio|tty|pty|file:portname[=portpath]\
[,[@]stdio|tty|pty|file:portname[=portpath][:socket_type]]`
  *receding with @ marks the port as a console port,
   otherwise it is a normal virtio-serial port
  *The portpath can be omitted when backend is stdio or pty.
2. for virtio input, the generated launch script as below.
`<name>:<phys>,id=<anyString>`
The launch script will automatically find the specific /dev/input/eventX
according to the event name and phys got from board.xml.
