test/drivers/gpio: add tests for new API

Browse source 
Test that the new port API functions all behave as expected, including
physical vs logical level for input and output as well as masked and
set-based output operations.  Also tests the new pin API functions.

For running on real hardware this test now uses a local test-specific
devicetree binding.  For build-only tests any platform with a GPIO
alias should be tested.

The new code increases flash requirements so add a filter to exclude
platforms that won't link.
