refactor(config): config metadata (@Miodec) (monkeytypegame#6753)

Create config metadata object
Move all the special code on config change to config listeners
Create a generic set function which will work with the metadata object
to update any config key
Update all setters to use the generic set.
(Later probably only use the generic settter and remove all the specific
ones)
Also orders config groups and config schema.
