f3325a1cb8 [helpers/killer] Force to platform XCB 
Summary:
The killer can only kill X11 windows. It is also only invoked for Client
and not for ShellClient. The tool interacts with QX11Info which means it
would crash if tried to use on Wayland.

Thus force platform xcb on the tool.

Test Plan: Killer shows for Xwayland windows.

7b0676ebaf Include <errno.h> in waylandclipboard.cpp 
Summary:
`errno.h` needs to be includes, as `errno`, `EAGAIN` and `EWOULDBLOCK` are used.

1d24264e45 [helpers/xclipboradsync] Ensure that KWayland::Client connects through the passed fd 
One needs to call ConnectionThread::setSocketFd in order to not have it
connect through the normal socket.

As WAYLAND_SOCKET is set the implementation would call the correct
functionality anyway. This change only ensures that no wrong debug
message gets logged.

3493e97655 Support for syncing the clipboard from X11 to Wayland and vice versa 
Summary:
The clipboard sync is done by a dedicated helper binary launched by
KWin. This helper binary is forced to xcb platform to piggy-back on
Qt's implementation of the X11 clipboard. In addition it implements
the Wayland clipboard - which is much simpler. Reading the Wayland
clipboard is based on the implementation in QtWayland.

KWin internally knows the DataDeviceInterface belonging to the helper
application. Whenever an xwayland client is focussed, this DataDevice
is allowed to set the selection and KWin manually updates the current
selection in the SeatInterface. By that the sync from X11 to Wayland
is implemented. When afterwards a Wayland client is selected, it's sent
the current selection which references the X clipboard and a data
transfer can be initiated in the normal Wayland way.

For the other direction KWin sends the current selection to the helper's
DataDevice whenever an xwayland window is focused. The helper application
reads the Wayland clipboard and sets it on the X11 clipboard. Thus the
Wayland clipboard is synced to X11.

The approach used here will also be useful for implementing a clipboard
manager (aka klipper).

Currently the implementation is not yet fully completed. We need to
make sure that the helper application gets restarted in case of a crash.

Test Plan: See added test case
