UEFI spec defined ACPI Tables at boot time can be contained in memory of
type EfiACPIReclaimMemory or EfiAcpiMemoryNVS, although InstallAcpiTable
with AcpiTableProtocol will only allocate memory with type
EfiACPIReclaimMemory (Except FACS).
This patch provides an optional method controlled by PCD to avoid using
EfiACPIReclaimMemory, by setting the PCD PcdNoACPIReclaimMemory to TRUE,
all ACPI allocated memory will use EfiAcpiMemoryNVS instead.

AHCI commands are retried internally which prevents platform feature
like drive password to process correctly entered password on subsequent
attempts. PCD allows the platform to determine the number of retries.

The security researcher found that we can get control after NEM disable.
The reason is that the flash content reside in NEM at startup and the
code will get the content from flash directly after disable NEM.
To avoid this vulnerability, the feature will copy the PEIMs from
temporary memory to permanent memory and only execute the code in
permanent memory.
The vulnerability is exist in physical platform and haven't report in
virtual platform, so the virtual can disable the feature currently.
When enable the PcdMigrateTemporaryRamFirmwareVolumes, always shadow
all PEIMs no matter the condition of PcdShadowPeimOnBoot or
PcdShadowPeimOnS3Boot.

Current UpdateCapsule service will reject all non-reset capsule images and
return EFI_OUT_OF_RESOURCE if the system is at runtime. This will block a
platform CapsuleLib from implementing ProcessCapsuleImage() with runtime
capsule processing capability.
This patch removes this restriction. The change is controled by a feature
PCD PcdSupportProcessCapsuleAtRuntime, and the default value is FALSE
which means not enable this feature.

UEFI-Capsule-on-Disk-Introducation
This patch will add Capsule On Disk related definition, including
GUID, PPI and PCDs:
The Capsule On Disk Name GUID indicates the capsule is to store
Capsule On Disk file names.
The Pei Capsule On Disk PPI provides service to retrieve capsules
from Capsule On Disk temp relocation file on mass storage devices
and create capsule hob for these capsules.
Pei Boot In CapsuleOnDisk Mode Ppi indicates current boot mode is
capsule on disk mode.
PcdCapsuleOnDiskSupport is used to enable/disable Capsule On Disk.
PcdCapsuleInRamSupport is used to enable/disable Capsule In Ram.
PcdCoDRelocationFileName specifies the Capsule On Disk temp
relocation file name.
PcdCodRelocationDevPath specifies platform specific device to store
Capsule On Disk temp relocation file.
