This patch updates the GetMemoryRegion() function to handle the case
where there is no mapping for the requested address.
The original logic for the ARM would hit an ASSERT after
GetMemoryRegionPage() returned EFI_SUCCESS but did not update The
RegionLength parameter.
The original logic for the AARCH64 would never initialize the
RegionLength parameter to zero and return EFI_SUCCESS after
traversing an unknown number of pages.
To fix this, update the logic for both architecture to return
EFI_NO_MAPPING if the BaseAddress being checked is unmapped.

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
modify smm page table when ReadyToLock.

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.
