rtc_gpio_set_direction_in_sleep() function

RTC GPIO set direction in deep sleep mode or disable sleep status (default). In some application scenarios, IO needs to have another states during deep sleep. NOTE: ESP32 supports INPUT_ONLY mode. The rest targets support INPUT_ONLY, OUTPUT_ONLY, INPUT_OUTPUT mode.
