We declared `cycle_state` struct in `labwc.h` and `cycle_osd_scene` struct in `output.h`, which was unclean in terms of separation of concerns. So this commit firstly moves `cycle_state` to `cycle.h`, then replaces `cycle_osd_scene` in `output.h` with `cycle_osd_output` in `cycle.h` which is dynamically allocated in a similar manner to `session_lock_output`. This ensures that all states about alt-tabbing are stored in `server->cycle`. Also, this commit fixes a rare memory leak in `output->cycle_osd.items` when an output is destroyed while alt-tabbing, by freeing it when the osd tree is destroyed.
