* xwayland: add destructor to CXWM and free resource

the wl_event_resource was running upon destruction of the compositor
causing a null pointer segfault in onX11Event so ensure the event is
removed upon destruction, also free the memory allocated by
xcb_errors_context_new and finally call xcb_disconnect on the connection
to free the fd and its memory.

* hyprctl: dont leak the fd on destruction

add a destructor and properly free the fd on destruction

* eventloop: add destructor and free event source

properly free the wl_event_source upon destruction.
