@brief Bind the GPIO with the ETM event

@note Calling this function multiple times with different GPIO number can override the previous setting immediately. @note Only GPIO ETM object can call this function

@param[in] event ETM event handle that created by gpio_new_etm_event @param[in] gpio_num GPIO number that can trigger the ETM event @return - ESP_OK: Set the GPIO for ETM event successfully - ESP_ERR_INVALID_ARG: Set the GPIO for ETM event failed because of invalid argument, e.g. GPIO is not input capable, ETM event is not of GPIO type - ESP_FAIL: Set the GPIO for ETM event failed because of other reasons
