@brief Combine a peripheral signal which tagged as output attribute with a GPIO.
@note There’s no limitation on the number of signals that a GPIO can combine with.
@param gpio_num GPIO number
@param signal_idx Peripheral signal index (tagged as output attribute). Particularly, SIG_GPIO_OUT_IDX means disconnect GPIO and other peripherals. Only the GPIO driver can control the output level.
@param out_inv Whether to signal to be inverted or not
@param oen_inv Whether the output enable control is inverted or not
