feat(rgbcw_lightbulb): move Daybetter here from rgbwc_lightbulb.

Issue #5880 requested this device to be specifically added to rgbwc_lightbulb,
but the user's detailed justification was that one of the scene's matches.

The scenes can be arbitrarily written through the text entity, so matching of scenes
is secondary to other concerns such as the direction of the color temperature.

Issue #6293
