GH-39: Prioritize command classes for interview

First time we use COMMAND_CLASS_VERSION, query its own version supported.

Prioritize COMMAND_CLASS_MANUFACTURER_SPECIFIC before others.
UAM rules can match unique device model, so we could override
supported command class version attributes for matching device model.
