esp_sleep_enable_ext1_wakeup() function

- ESP_OK on success - ESP_ERR_INVALID_ARG if io_mask is zero,, or mode is invalid

This function does not modify pin configuration. The pins are configured in esp_deep_sleep_start/esp_light_sleep_start, immediately before entering sleep mode. Internal pullups and pulldowns don't work when RTC peripherals are shut down. In this case, external resistors need to be added. Alternatively, RTC peripherals (and pullups/pulldowns) may be kept enabled using esp_sleep_pd_config function. If we turn off the ``RTC_PERIPH`` domain or certain chips lack the ``RTC_PERIPH`` domain, we will use the HOLD feature to maintain the pull-up and pull-down on the pins during sleep. HOLD feature will be acted on the pin internally before the system entering sleep, and this can further reduce power consumption. Call this func will reset the previous ext1 configuration. This function will be deprecated in release/v6.0. Please switch to use `esp_sleep_enable_ext1_wakeup_io` and `esp_sleep_disable_ext1_wakeup_io`
