REVISION SUMMARY
  Xkbcommon does not localize the layout names. We always get the US
  English variant. KWin so far passed the strings from xkbcommon directly
  to UI visible parts such as the Plasma OSD. This results in not
  translated elements in our UI.
  
  As I figured out today the translations exist in the domain
  xkeyboard-config. Passing the strings from xkbcommon through this domain
  gives us translated layouts.
  
  Unfortunately the xkeyboard-config is not installed by default on all
  distributions. E.g. on ubuntu/neon one needs to install xkb-data-i18n
  to have the translations available.

TEST PLAN
  Untested as I fail to start Plasma/5.8 KWin on my dev system
