Improve deCONZ lights supported_color_modes and tests

Breaking change

Proposed change

Follow up PR to #51656, where test coverage declined.
Library change Kane610/deconz@v79...v80 (only PR 123 affects functionality).

Improve reflecting light state changes to relevant groups in library. Previously only one lights supported features would be read, after this change all lights connected to the group will be considered. This means a group can better reflect different types of lights together, earlier a group could be seen as only supporting brightness even though it also had a light supporting XY color mode.
