Make it possible to connect to a createSurface signal

Remove the QWaylandSurface factory function from QWaylandCompositor.
Add a default constructor to QWaylandSurface and a initialize function.
Add som housekeeping code in debug builds that ensures the user calls
initialize.
Add a fallback factory function on the compositor if the user is fine
with getting the default implementation of QWaylandSurface or
QWaylandQuickSurface
