Adds an SMM SMRAM save-state map for AMD processors.
SMRAM save state maps for the AMD processor family are now supported.
Save state map structure is added based on
AMD64 Architecture Programmer's Manual, Volume 2, Section 10.2.
The AMD legacy save state map for 32-bit architecture is defined.
The AMD64 save state map for 64-bit architecture is defined.
Also added Amd/SmramSaveStateMap.h to IgnoreFiles of EccCheck,
because structures defined in this file are derived from
Intel/SmramSaveStateMap.h.

Clear CR0.WP before modify smm page table. Currently, there is
an assumption that smm pagetable is always RW before ReadyToLock.
However, when AMD SEV is enabled, FvbServicesSmm driver calls
MemEncryptSevClearMmioPageEncMask to clear AddressEncMask bit
in smm page table for this range:
[PcdOvmfFdBaseAddress,PcdOvmfFdBaseAddress+PcdOvmfFirmwareFdSize]
If page slpit happens in this process, new memory for smm page
table is allocated. Then the newly allocated page table memory
is marked as RO in smm page table in this FvbServicesSmm driver,
which may lead to PF if smm code doesn't clear CR0.WP before

Remove code that sets AddressEncMask for non-leaf entries when
modifing smm page table by MemEncryptSevLib. In FvbServicesSmm
driver, it calls MemEncryptSevClearMmioPageEncMask to clear
AddressEncMask bit in page table for a specific range. In AMD
SEV feature, this AddressEncMask bit in page table is used to
indicate if the memory is guest private memory or shared memory.
But all memory accessed by the hardware page table walker is
treated as encrypted, regardless of whether the encryption bit
is present. So remove the code to set the EncMask bit for smm
non-leaf entries doesn't impact AMD SEV feature.
The reason encryption mask should not be set for non-leaf
entries is because CpuPageTableLib doesn't consume encryption
mask PCD. In PiSmmCpuDxeSmm module, it will use CpuPageTableLib
to modify smm page table in next patch. The encryption mask is
overlapped with the PageTableBaseAddress field of non-leaf page
table entries. If the encryption mask is set for smm non-leaf
page table entries, issue happens when CpuPageTableLib code
use the non-leaf entry PageTableBaseAddress field with the
encryption mask set to find the next level page table.

Currently, ArmSetMemoryAttributes () takes a combination of
EFI_MEMORY_xx constants describing the memory type and permission
attributes that should be set on a region of memory. In cases where the
memory type is omitted, we assume that the memory permissions being set
are final, and that existing memory permissions can be discarded.
This is problematic, because we aim to map memory non-executable
(EFI_MEMORY_XP) by default, and only relax this requirement for code
regions that are mapped read-only (EFI_MEMORY_RO). Currently, setting
one permission clears the other, and so code managing these permissions
has to be aware of the existing permissions in order to be able to
preserve them, and this is not always tractable (e.g., the UEFI memory
attribute protocol implements an abstraction that promises to preserve
memory permissions that it is not operating on explicitly).
So let's add an AttributeMask parameter to ArmSetMemoryAttributes(),
which is permitted to be non-zero if no memory type is being provided,
in which case only memory permission attributes covered in the mask will
be affected by the update.
