wayland: use a low priority FDM hook to flush the wayland socket

Browse source 
This way, we don't have to manually insert flushes in code paths that
may execute outside of a wl_display_dispatch_pending().

(Those that execute inside a wl_display_dispatch_pending() are subject
to the flush performed at the end of the normal wayland FDM handler).
