Add LIFX Thing properties

[wborn]

This PR adds adds the following Thing properties to LIFX lights:

• hostVersion
• macAddress
• productId
• productName
• productVersion
• vendorId
• vendorName
• wifiVersion
• zones (only for lights that have MultiZone control, e.g. LIFX Z)

All properties (except for zones) are added during discovery. Apparently new property values from discovery results are not updated. E.g. when you would manually update the firmware via the LIFX app. Also these properties are not added to Things that already exist. I've submitted issue #3323 for this.

Furthermore I've removed the StateMeshFirmwareResponse GetMeshFirmwareRequest packets because these are remnants of the old LIFX protocol. StateMeshFirmwareResponse causes issues when response packets are received because it has the same packet type as StateHostFirmwareResponse.

LifxLightDiscovery will now also detect and skip lights that are not yet supported by the binding.
