Support multiple deCONZ gateways (#22449)

* Store gateways inside a dict in deconz domain

* Make reachable events gateway specific

* Gateway shall always exist

* Adapt new device signalling to support multiple gateways

* Services follow gateway master

* Working on unload entry

* Make unload and master handover work
Improve tests for init

* Fix config flow

* Fix linting

* Clean up init tests

* Clean up hassio discovery to fit with the rest
