OvmfPkg/CpuHotplugSmm: add EjectCpu()
Add EjectCpu(), which handles the CPU ejection, and provides a holding
area for said CPUs. It is called via SmmCpuFeaturesRendezvousExit(),
at the tail end of the SMI handling.
Also UnplugCpus() now stashes QEMU Selectors of CPUs which need to be
ejected in CPU_HOT_EJECT_DATA.QemuSelectorMap. This is used by
EjectCpu() to identify CPUs marked for ejection.
