UefiCpuPkg/CpuDxe: clean up PAGE_TABLE_LIB_PAGING_CONTEXT usage.
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1039
Current implementation not checks system mode before using
PAGE_TABLE_LIB_PAGING_CONTEXT.ContextData.X64 or
PAGE_TABLE_LIB_PAGING_CONTEXT.ContextData.Ia32. This patch check the
mode before using the correct one.
