Add USB support to incus info --resources

[stgraber]

Currently incus info --resources doesn't show USB device at all.

It would be good to add a concise listing of USB devices based on the data already available in the resources API (/1.0/resources).

This list should at least include:

• Device vendor (name and id)
• Device product (name and id)
• Bus and device address
• Serial number (if present)

So looking at something not too dissimilar to the lsusb output.
