Add a config option 'EnableWattsUpPro' to disable the Watts Up Pro device

Annoyingly, the device used in the Watts Up Pro device seems to be a generic
USB->serial adaptor, which means it doesn't have a unique vendor and product
ID. If we try to probe for the WUP device, we can actually upset other devices
that are not expecing to be probed. This fixes #33846 although we actually
still need to be more strict in detecting a true WUP device.
