RasmusNylander 4e65c4dae4 LibKeyboard: Change some Optional<T> returns to ErrorOr<T>
Makes CharacterMapFile::load_from_file and CharacterMap::load_from_file
return ErrorOr instead of Optional. This makes them a little nicer to
use and a little easier to read, as they seem to have been approximating
this.
