1. CapsuleLongModeBuffer variable should not have EFI_VARIABLE_RUNTIME_ACCESS attribute.
2. CapsuleLongModeBuffer variable should be set to Read-Only. It should not be changed by someone else.
3. Introduce a new PCD PcdIdentifyMappingPageTablePtr to share the same range of page table between AcpiS3 and Capsule.
4. Capsule stack size is allocated from PcdCapsulePeiLongModeStackSize.
