UefiCpuPkg: Fix IA32 build failure in CpuPageTableLib.inf

Browse Source 
The definition of IA32_MAP_ATTRIBUTE has 64 bits, and one of the bit
field PageTableBaseAddress is from bit 12 to bit 52. This means if the
compiler treats the 64bits value as two UINT32 value, the field
PageTableBaseAddress spans two UINT32 value. That's why when building in
NOOPT mode in IA32, the below issue is noticed:
	unresolved external symbol __allshl
This patch fix the build failure by seperate field PageTableBaseAddress
into two fields, make sure no field spans two UINT32 value.
