intel: improve computing device and driver uuid

Provide a new uuid function as a more generic form to generate uuids that can distinguish devices, contexts composed of devices and their driver, or just the software driver. The uuids of anv device and driver uuids in all places are updated accordingly. Some drivers still uses the legacy function to create device uuids, and we should address these later.
