CAPI IRQ controller GPIO external-interrupt integration tests.

These are integration tests, not unit tests: every case raises a REAL interrupt by driving a GPIO output pin that is externally wired to a GPIO input pin (the same JAx loopback pair used by test_gpio), and observes it arriving through the CAPI IRQ contract. We test the CAPI idea – connect a callback, gate it with enable/disable and the global switch, deliver the argument, re-point the handler – not the underlying vendor BSP.
To run this suite on a new platform, implement three hooks (declared in common_data.h, defined in that platform's main.c – not here, and not tied to any vendor):
platform_gpio_irq_arm(&irq_line) route the loopback input pin to an IRQ and return its CAPI line; -ENOTSUP if the board has no GPIO-IRQ path (suite skips). platform_gpio_irq_ack() clear that pin as the source, called from inside the ISR. platform_gpio_irq_disarm() mask the pin's interrupt again.
Everything else here is pure CAPI.
