Jeff Fan 45e3440ac2 UefiCpuPkg/PiSmmCpuDxeSmm: Place AP to 32bit protected mode on S3 path 
On S3 path, we may transfer to long mode (if DXE is long mode) to restore CPU
contexts with CR3 = SmmS3Cr3 (in SMM). AP will execute hlt-loop after CPU
contexts restoration. Once one NMI or SMI happens, APs may exit from hlt state
and execute the instruction after HLT instruction. If APs are running on long
mode, page table is required to fetch the instruction. However, CR3 pointer to
page table in SMM. APs will crash.

This fix is to disable long mode on APs and transfer to 32bit protected mode to
execute hlt-loop. Then CR3 and page table will no longer be required.
