chore(developer): cleanup kmc-keyboard-info interface

Moves responsibility for loading .kps into kmc-keyboard-info, away from
the caller, and removes other fields with kmc-keyboard-info can
calculate by itself.

Have not moved project parsing into kmc-keyboard-info, because that's a
bigger job, as currently that is mostly happening within kmc itself. A
project for a future version I think.
