usb: cdc: Add unique PIDs for each sample

Unique PID is required for each sample in order
to be recognized by host.

When creating a new sample:
- Add USB_PID_<SAMPLE_NAME>_SAMPLE
  in samples/subsys/usb/usb_pid.Kconfig
- Create Kconfig file in your sample's subdirectory, containing:
  config USB_DEVICE_PID
	default USB_PID_<SAMPLE_NAME>_SAMPLE

 Steering Committee, may allocate other USB Product IDs based on well-motivated
 and documented requests.
 
+Each USB sample has its own unique Product ID.
+When adding a new sample, add a new entry in :file:`samples/subsys/usb/usb_pid.Kconfig`
+and a Kconfig file inside your sample subdirectory.
+The following Product IDs are currently used:
