Zhiguang Liu 13b97736c8 UefiCpuPkg: Fix SMM code hangs when InitPaging

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4246

In function InitPaging, NumberOfPml5Entries is calculated by below code
NumberOfPml5Entries = (UINTN)LShiftU64 (1, SizeOfMemorySpace - 48);
If the SizeOfMemorySpace is larger than 48, NumberOfPml5Entries will be
larger than 1. However, this doesn't make sense if the hardware doesn't
support 5 level page table.
