Remove config singleton (#2951)

* Remove unused function

* Refactor deprecation warning

* Modules take config as parameter instead of using the singleton

* Bar take config as parameter instead of using the singleton

* Renderer take config as parameter instead of using the singleton

* Legacy Tray Manager take config as parameter instead of using the singleton

* Screen take config as parameter instead of using the singleton

* Controller take config as parameter instead of using the singleton

* Remove the config singleton

* Apply review suggestion
