The IPI HLT test simulates a scenario where a pending event is present while the HLT instruction is executed.

This test evaluates the idle HLT intercept feature of the AMD architecture, if available. If the feature is not present, the test exercises halt-exits/guest-entry for pending interrupts. It can be extended in the future to include cross-vCPU IPI testing.
