Fix Double Event

- Removed: webui_interface_get_bind_id()
- Add: webui_event_t -> size_t bind_id

Wrappers that have internal-event-handler may call by mistake the same callback twice when app use all-events. To fix this issue, simply wrappers should replace `webui_interface_get_window_id()` by `e.bind_id`.
