test/py: gpio: Add gpio pins generic test

Add gpio pins generic test for the set of gpio pin list to test various
gpio related functionality, such as the input, set, clear, and toggle,
it also tests the input and output functionality for shorted gpio pins.
This test depends on boardenv* configuration to define gpio pins names.
