Some globals are static and it doesn't make sense to destroy them before the wl_display. For instance, wl_compositor should be created before the display is started and shouldn't be destroyed. For these globals, we can simplify the code by removing the destructor and stop keeping track of wl_resources (these will be destroyed with the wl_display by libwayland).
