tests: drivers: gpio: gpio_api_1pin: Add AW9523B test configuration

Add test configuration for Awinic AW9523B.

This device is a GPIO Expander, and no boards currently implement it.
Define the connection that connects it via the Arduino header and
define a fixture to enable it.

This has been confirmed with nucleo_h503rb.
