OvmfPkg/CpuHotplugSmm: add function for collecting CPUs with events
Add a function that collects the APIC IDs of CPUs that have just been
hot-plugged, or are about to be hot-unplugged.
Pending events are only located and never cleared; QEMU's AML needs the
firmware to leave the status bits intact in the hotplug register block.
