What to do:
1. Remove a hidden assumption "No SMM driver writes BootScript between
SmmReadyToLock and S3SleepEntryCallback".
1.1. Use SmmExitBootServices and SmmLegacyBoot notification to record
AtRuntime flag.
1.2. Use mBootScriptDataBootTimeGuid LockBox to save boot time boot
script data to handle potential INSERT boot script at runtime in SMM.
2. Do not depend on OS to help restore ACPINvs data and use
EfiReservedMemoryType instead of EfiACPIMemoryNVS.
2.1. Use mBootScriptSmmPrivateDataGuid LockBox to save boot script
SMM private data with BackFromS3 = TRUE at runtime. S3 resume
will help restore it to tell the Library the system is back
from S3.
Why to do:
1. The hidden assumption "No SMM driver writes BootScript between
SmmReadyToLock and S3SleepEntryCallback" will cause confusion to
the library's consumer and block the usage of "SMM driver writes
BootScript after SmmReadyToLock". So Remove the assumption.
2. In original code, there might be a corner case that malicious
code patch ACPINvs boot TableLength field same as SMM boot script.
So that it can skip the table restore. The impact is that BootScript
in SMM may be overridden by malicious code.
--------------------
CopyMem ((VOID*)&TableHeader, (VOID*)mS3BootScriptTablePtr->TableBase, sizeof(EFI_BOOT_SCRIPT_TABLE_HEADER));
if (mS3BootScriptTablePtr->TableLength + sizeof(EFI_BOOT_SCRIPT_TERMINATE) != TableHeader.TableLength) { // TableLength is in NVS
......
//
// NOTE: We should NOT use TableHeader.TableLength, because it is already updated to be whole length.
//
mS3BootScriptTablePtr->TableLength = (UINT32)(mLockBoxLength - sizeof(EFI_BOOT_SCRIPT_TERMINATE)); ? This line can be skipped.
--------------------
So use EfiReservedMemoryType instead of EfiACPIMemoryNVS as the code
has been updated to not depend on OS to help restore ACPINvs data.

This feature is added for UEFI spec that says
"Stack may be marked as non-executable in identity mapped page tables".
A PCD PcdSetNxForStack is added to turn on/off this feature, and it is
FALSE by default.

v2 changelog:
Check CurrentPeimHandle to check the matched PeimHandle.
Add check point to ShadowPeiCore based on PCD.
v1 changelog:
PeiCore LoadImage always shadow itself and PEIM on normal boot after
the physical memory is installed. On the emulator platform, the shadow
may be not necessary. To support such usage, new PCD PcdShadowPeimOnBoot
is introduced to specify whether loads PEIM in memory by default.

Currently, Max Authenticated variable size = Max Regular Variable Size,
and both are controlled via a single PCD:
gEfiMdeModulePkgTokenSpaceGuid.PcdMaxVariableSize.
This PCD is introduced to control the Max Size of Authenticated Variable.
