3djc/enhance companion get capability (#4243)

* Add info on switches/sliders/pots setup when delivered from factory (other calls return user installed max possible)

* Fix

* getCapability() : Refine actoryInstalledSwitches, add NumTrimSwitches, remove FactoryInstalledPots & FactoryInstalledSliders;
GeneralSettings() initialization : Use `FactoryInstalledSwitches` count instead of `Switches` for default setup, and also set up correct number of sliders for X9E (4) and X7 (0).

* Enum order cosmetics.  [ci skip]
