wayland: iconify/deiconify and post_dispatch struct field

- Remove !wwin->frame early exits in wIconifyWindow/wDeiconifyWindow
- Guard frame-dependent code with wwin->frame checks
- Implement wl_client_set_state (scene node enable/disable)
- Add post_dispatch to W_EventBackend struct (.h + .h.in)
- Fix client_snapshot, animateResize, and frame refs for Wayland
