[tradfri] Add switch channel to Tradfri lightning devices #14815

Further details

In order to simplify integration with OpenHAB 3.x and forward, adding a Switch channel to the tradfri binding seems mandatory. It would align this to the hue binding mechanism.

Your Environment

Version used: OpenHAB 3.4.3, org.openhab.binding.tradfri 3.4.3
Environment: Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.17+10-LTS-269, mixed mode)
Operating System and version Debian GNU/Linux 11 (bullseye)

Feasibility analysis:

Today, the brightness channel is used for both setOnOffState and setBrightness :
- based on probing of the PrimitiveType received
- while this corresponds to different IPSO Objects (ONOFF / 5850 and DIMMER / 5851)

Proposed action plan would be to:

add a switch channel with typeId = "system.power" to thing types 0100, 0220, 0210 (consistent with hue binding)
keep the PrimitiveType probing for retro-compatibility on the brghtness channel.
