UefiCpuPkg/DxeMpLib: Allocate below 4GB mem for AsmRelocateApLoopFunc
Current implementation just allocates reserve memory for AsmRelocateApLoopFunc.
It not be safe because APs will be placed into 32bit protected mode on long mode
DXE. This reserve memory must be located below 4GB memory.
This fix is to allocate < 4GB memory for AsmRelocateApLoopFunc.
