tests: lib: devicetree: api: Add tests for IRQ_INTC_* macros

Browse source 
Extend api test suite to cover the new devicetree macros. This
includes extending the devicetree overlay with two new bindings:

- GPIO device which is also an interrupt controller
- interrupt holder using interrupts-extended to point to both
  existing interrupt controller test_intc, and the newly added
  GPIO device
