wayland: Phase 51 — multi-client: two simultaneous toplevels managed cleanly 

Run two weston-simple-shm processes in parallel during the smoke test
and verify that all three toplevels (one from the single-client section
plus two from the parallel section) are managed and unmanaged without
crashing the compositor.  The synthetic-ID counter, focus chain, and
wUnmanageWindow path all survive the multi-client scenario.
