CAN: Implement QCanBusDevice::deviceInfo() in the plugins

* PasstruCAN: Untested
* PeakCAN:    Tested on Windows with PCAN-USB Pro FD.
* SocketCAN:  Tested on Linux with virtual and real hardware.
* SystecCAN:  Tested on Windows with USBcanmodul2.
* TinyCAN:    Untested
* VectorCAN:  Tested with the virtual Vector interface.
* VirtualCAN: Tested on Windows and Linux.

Pick-to: 6.2
