[Patch V5 05/22] UefiCpuPkg/CpuPageTableLib:Clear PageSize bit(Bit7) for non-leaf

["duntan" <dun.tan@intel.com>]

Clear PageSize bit(Bit7) for non-leaf entry in PageTableLibSetPnle.
This function is used to set non-leaf entry attributes so it should
make sure that the PageSize bit of the entry should be 0.
