[RFC PATCH v3 43/43] MdeModulePkg/DxeCore: Perform the CPU protocol finalization support

["Lendacky, Thomas" <thomas.lendacky@amd.com>]

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2198

Invoke the CPU finalization function when exiting boot services. This
allows for DXE and the MP Library to properly setup and park APs for an
SEV-ES guest so that they can be booted in the OS.
