Fix HomeKit behavior with lights supporting color and temperature

[frenck]

Description:

If a light supports both the Hue and ColorTemperature characteristic types, HomeKit will actually keep both states separate and active and the same time.

This causes a problem in several ways since we no longer know what the truth is at this point. This is the best visible from the Home app itself:

(sorry for the low-quality GIF, for more examples, see first linked issue below)

The only option we have is to decide what to use. This PR implements a change that prevents exposing the ColorTemperature characteristic when the light supports Hue as well (like Hue).

It resolves the issues linked below, and most likely issues with people using a lot of Philips Hue bulb trying to apply scenes to a bunch of those (which may cause some bulbs not to change as set in the scene).

In the Home apps, even with only Hue set, the color temperature selection remains available. However, colors are sent to Home Assistant, instead of a temperature.
