REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2008 MpInitLib is the library that's responsible to wake up APs to provide MP PPI and Protocol services. The patch synchronizes BSP's CR4.LA57 to each AP's CR4.LA57. Without this change, AP may enter to GP fault when BSP's 5-level page table is set to AP during AP wakes up.
