Move led control to firmware

[Koenkk]

As discussed in Koenkk/Z-Stack-firmware#203 (comment) the LED control responsibility should move to the firmware. With the current implementation herdsman sets the LED on/off when joining is enabled, this breaks LEDs for custom firmwares.

With this change setLED() and supportsLED() are removed from the controller, herdsman will no longer control the LEDs when joining is enabled/disabled.

For ZStack adapters:

• For firmwares having revision >= 20211029:

  • ledControl will not be called when joining is enabled/disabled
  • If disable_led: true is set LED control is called with {ledid: 0xFF, mode: 5}. When ledControl is called with mode: 5 the firmware should disable all leds.

• For firmwares having revision < 20211029, the behaviour isn't changed ledControl is still called when joining is enabled/disabled. (this is to avoid a breaking change on firmwares not turning on leds when joining is enbaled/disabled)

• I will provide new firmwares which have internal LED control when joinig is enabled/disabled:

  • Z-Stack_Home_1.2: https://github.com/Koenkk/Z-Stack-firmware/tree/2671dbaa484b4a1ac724e77cc71f2155fbbf7628/coordinator/Z-Stack_Home_1.2
  • Z-Stack_3.x.0: TODO

• For Zigbee2MQTT this requires: Dont control leds zigbee2mqtt#9404
