REVISION SUMMARY
  Choose backend automatically, based on actually available
  plugins at runtime, independently of kwin compile options.
  Don't limit command line options too.

TEST PLAN
  compile kwin without some of backends. Then
  compile kwin with that backend separately, manually
  copy the appropriate plugin into plugins directory.
  Verify that `kwin_wayland --help` lists that option,
  and running kwin_wayland without arguments, with proper
  environment automatically selects proper backend plugin.
