qdev-monitor: Group "device_add help" and "info qdm" by category

Output is a long, unsorted list.  Not very helpful.  Print one list
per device category instead, with a header line identifying the
category, plus a list of uncategorized devices.  Print each list in
case-insenitive alphabetical order.

Devices with multiple categories are listed multiple times.
