UefiCpuPkg/PeiMpLib: Fix a system hang-in-pei issue.
GetWakeupBuffer() tries to find a below-1M free memory, it checks
whether the memory is allocated already in
CheckOverlapWithAllocatedBuffer(). When there is a memory allocation
hob (base = 0xff_00000000, size = 0x10000000),
CheckOverlapWithAllocateBuffer() truncates the base to 0 which causes
it always returns TRUE so GetWakeupBuffer() fails to find a below-1MB
memory.
The patch fixes this issue by using UINT64 type.
