Init CPU_HOT_EJECT_DATA, which will be used to share CPU ejection state between SmmCpuFeaturesLib (via PiSmmCpuDxeSmm) and CpuHotPlugSmm. The init happens via SmmCpuFeaturesSmmRelocationComplete(), and so it will run as part of the PiSmmCpuDxeSmm entry point function, PiCpuSmmEntry(). Once inited, CPU_HOT_EJECT_DATA is exposed via PcdCpuHotEjectDataAddress. The CPU hot-eject handler (CPU_HOT_EJECT_DATA->Handler) is setup when there is an ejection request via CpuHotplugSmm.
