Summary:
By changing all kcfg to have arg="true" we can pass in the same
KSharedConfigPtr into all effects. This allows to have fake config in
the tests and in the planned effect demo mode.
Also it means that we don't have to hardcode the name kwinrc into the
files. In the configs - where we cannot access the effectshandler - we
use the define KWIN_CONFIG which gets generated based on the compile
time arguments.

The usage has always been questionable as the thumbnails are
too small to properly recognize something.
Now BoxSwitch Effect has reach its end of life which would have
required to keep most of the code just for this thumbnail bar.
If required it would be better to integrate the normal QML based
TabBox to be rendered together with an effect.
