NativeWindow AbstractGraphicsDevice: Add 'unitID' attribute and getUniqueID()

Preparation to support multiple devices on one machine,
hence adding the unitID a unique ID/index of the associated GPU, or GPU affinity.

Adding getUniqueID() to return a cached semantic unique string id for the device.
This was removed from the temp. impl in JOGL's GLContext, added unitID.

All other changes just adapt to the above.
