Subject: QML API for xdg-shell

Exposes QWaylandXdgShell and QWaylandXdgSurface as QML types, along with
a new QWaylandXdgSurfaceItem.

All of this mirrors the implementation of wl_shell closely. The biggest
difference is how resize is handled.

There is now some duplication in the window chrome implementation of the
pure-qml compositor. This may be improved by refactoring the existing
API for shell extensions.
