The constants that need to be passed to gpio_matrix_in and gpio_matrix_out to detach an input or output pin from a peripheral vary by platform. Use SIG_GPIO_OUT_IDX to detach an output, and GPIO_MATRIX_CONST_ONE_INPUT and GPIO_MATRIX_CONST_ZERO_INPUT to detach an input. ESP32 before IDF 4.0 didn't define GPIO_MATRIX_CONST_*_INPUT, so add compatibility #defines for GPIO_FUNC_IN_LOW/HIGH. GPIO_FUNC_IN_LOW/HIGH exist in IDF 4.0+, but can't be used because they have the wrong values for ESP32-C3 at least in IDF 4.4.3 (https://github.com/espressif/esp-idf/issues/11737).
