Add ARM vCPU inject IRQ test

This patch aims to test the scenario where we inject an IRQ on a vCPU that does not have a TCB associated with it. Currently this results in the kernel crashing inside invokeVCPUInjectIRQ. This test aims to confirm that the eventual fix to the kernel is correct. Signed-off-by: Ivan Velickovic <[email protected]>
