Expose surface's client to QML

Introduce QWaylandClient class that wraps wl_client credentials
and has a method to destroy the client.

Add QWaylandClient object as a QWaylandSurface property.

This come in handy for example when the compositor wants to kill the
process of an unresponsive surface or wants to know client credentails.

WaylandClient typedef is now useless thus is replaced by QWaylandClient.
