config_tools: refine virtio in launch script
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.
