Previous DxeCore FwVol code will cache whole FvMain FV from flash that may be
uncached if platform reports FvMain FVB, it will impact DXE performance.
The code already has file level cache, so don’t need to cache memory mapped IO FV.
It can also reduce memory consumption of caching memory mapped IO FVs.

2. DxeMain will get Vector Handoff Table GUIDed HOB to install configuration table if it has.
3. Updated CPU Exception Handler Library to provide 3 new APIs to replace original one API and updated NULL instance accordingly.
4. Updated DxeMain/CapsuleX64/BootSriptExectorDxe to use the new API in CPU Exception Handler Lib.

1. Update SecurityManagementLib to support SAP2 and SAP services.
2. Update SecurityStub driver to produce SAP2 and SAP protocol both.
3. Update DxeCore and SmmCore to use SAP2 and SAP service to verify Image.
4. Update DxeCore ConnectController() to use SAP2 service to check user permission.

1. For LoadImage() service, EFI_ACCESS_DENIED return status is added, and EFI_SECURITY_VIOLATION return status description is updated. Meanwhile, EFI_PE32_IMAGE_PROTOCOL. LoadPeImage() in MdeModulePkg is also updated to match LoadImage() service.

2) Change ARCHITECTURAL_PROTOCOL_ENTRY name to EFI_CORE_PROTOCOL_NOTIFY_ENTRY so it can be used for both Architectural Protocols and optional protocols that the DXE Core may use. Also remove BOOLEAN ArchitecturalProtocol field, so it is back to its original form.
3) Put mArchProtocols[] back to its original form, but add a NULL entry at the end so the end of the table can be easily detected in loops
4) Add mOptionalProtocols[] that at this time only has the SMM Base 2 Protocol in it.
5) Add NULL entry to mMissingProtocols[] so the end of the table can be easily detected.
6) Update all loops on mArchProtocols[], mOptionalProtocols, and mMissingProtocols[] to remove Index(s) and simply looks for a NULL ProtocolGuid to find the end of the table.
7) Update protocol notify events to pass the associated EFI_CORE_PROTOCOL_NOTIFY_ENTRY * as the Context parameter. This simplifies GenericProtocolNotify() by completely eliminating the search loop.

PI 1.2 SMM Drivers are allowed to call UEFI/DXE services and Protocols from the entry point of the PI 1.2 SMM Driver. These UEFI/DXE services and Protocols may directly or indirectly calls the UEFI Boot Services RaiseTPL() and RestoreTPL(). These UEFI Boot Services use the CPU Architectural Protocol to enable interrupts if the TPL level is below TPL_HIGH_LEVEL and enable interrupts of the TPL is at TPL_HIGH_LEVEL. Interrupts should be masked while executing SMM drivers, so if a direct or indirect call to the UEFI Boot Service RestoreTPL() would enable interrupts, then an interrupt could be incorrectly delivered in SMM context.
The solution is for the DXE Core to register for the PI 1.2 SMM Base2 Protocol. If that protocol is present in the platform, then the DXE Core can use the SMM Base 2 Protocol's InSmm() function to determine if the platform is currently executing in SMM content. If the current context is in SMM, then do not allow any requests to be forwarded to the CPU Architecture Protocol to enable interrupts.

EFI_SIGNATURE_16 -> SIGNATURE_16
EFI_SIGNATURE_32 -> SIGNATURE_32
EFI_SIGNATURE_64 -> SIGNATURE_64
EFI_FIELD_OFFSET -> OFFSET_OF
EFI_MAX_BIT -> MAX_BIT
EFI_MAX_ADDRESS -> MAX_ADDRESS
These macros are not defined in UEFI spec. It makes more sense to use the equivalent macros in Base.h to avoid alias.
