Add light color temperature intent support

[Moonlight63]

Proposed change

This is step one to resolving a feature request for voice assist to support changing the color temperature of lights. We can change color, but color temperature is a different operation. I had a need for this myself, but there is also an open feature request for it here: home-assistant/intents#2059
Step two of this process will be to implement the intent sentence, but this function has to be available in core first because otherwise the intent has nothing to call :)

Closing this in favor of #118321 which adds temperature via the newer optional slots mechanism.

Thank you for sorting that. I hadn't gotten a chance to change to the new system.
