Subject: Create a general ShellSurfaceItem to avoid duplication

XdgSurfaceItem and WlShellSurfaceItem have been removed in favor
of the more general ShellSurfaceItem. An XdgSurface or a WlShellSurface
can be assigned to the shellSurface property of a ShellSurfaceItem
and leaves open the possibility for additional shells.

A shared base class for QWaylandXdgSurface and QWaylandWlShellSurface
has been added which has a factory method for creating
a QWaylandQuickShellIntegration for that shell implementation.

The property "shellSurface" on the ShellSurfaceItem allows QML code to
attach to signals regardless of whether it's a WlShell or XdgShell
client. The pure-qml example has been updated to take advantage of this.
