1. CapsuleLongModeBuffer variable should not have EFI_VARIABLE_RUNTIME_ACCESS attribute.

Browse Source 
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.
