Add QNativeInterface::Private::QWaylandWindow

Allows to access the wl_surface, the setCustomMargins functions and
the object corresponding to the surface role of the surface.
Also adds  the xdg activation token functionality as it is needed by
another change in qtbase.
If the type passed to surfaceRole does not match the actual type of the
current surface role nullptr is returned.
QVariant is not used for transferring the surface role object because
it requires Q_DECLARE_OPAQUE_POINTER for storing and retrieving from
the QVariant. However QtWayland uses a plugin system for shell integrations
with known external plugins so it is not possible to centrally do this
for every possible pointer type. The alternative would be that plugin
and consumer delcare it both which does not make for an ergonomic API.
