Implement GIC-based ARM interrupt tests

[stephanosio]

The current interrupt test implementation for ARM assumes the availability of NVIC, which is only present on the Cortex-M devices.

A GIC-based implementation should be implemented for the Cortex-R and Cortex-A devices. Note that not all Cortex-R devices make use of the GIC, in which case the interrupt test should either be filtered out or executed partially.

TODO: Make sure that the dynamic interrupt test is aware of the always-enabled SGIs on some GIC variants (e.g. PL-390, GIC-400).
