Martin Flöser ea5e701164 [x11] Fix interactive point selection
Summary:
The support for interactive point selection was missing. This results in
the ColorPicker dbus API always returning an error on X11. We either need
to disable the ColorPicker on X11 or add support for this functionality.

As the X11 platform basically supports selecting a point in the
interactive window selection it makes more sense to add this missing
method in the platform than to disable support of color picker effect.

BUG: 387720
FIXED-IN: 5.12.1

Test Plan:
Run KWin/X11 on Xephyr and was able to pick a color and
kill a window
