[kwin-wayland] Add support for FullscreenShell

The FullscreenShell is a Wayland protocol provided by Weston to have exactly one surface per output. This is exactly what KWin needs. So in case the Wayland server we connect to provides the FullscreenShell we prefer it over the normal Shell and mapping our surface as fullscreen. The protocol is not yet part of wayland-client library, so the header and source file needs to be generated. This is done during the build process using the external tool wayland-scanner. The protocol description is copied from the Westion 1.5 sources. REVIEW: 119839
