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.
PcdCapsuleOnDiskSupport is used to enable/disable Capsule On Disk.
PcdCapsuleInRamSupport is used to enabble/disable Capsule In Ram.
PcdCoDRelocationFileName specifies the Capsule On Disk temp
relocation file name.
PcdCodRelocationDevPath specifies platform specific device to store
Capsule On Disk tem relocation file.

CoDCheckCapsuleOnDiskFlag() is to check if CapsuleOnDisk flag in
"OsIndications" Variable is enabled. It is used to indicate whether
capsule on disk is provisioned in normal boot path.
CoDClearCapsuleOnDiskFlag() is to to clear CapsuleOnDisk flags,
including "OsIndications" and "BootNext" variable.
CoDRelocateCapsule() is to relocate the capsules from EFI system
partition. Depends on PcdCapsuleInRamSupport, there are two solutions
to relocate the capsule on disk images:
When Capsule In Ram is supported, the Capsule On Disk images are
relocated into memory, and call UpdateCapsule() service to deliver
the capsules.
When Capsule In Ram is not supported, the Capsule On Disk images are
relocated into a temp file which will be stored in root directory on
a platform specific storage device. CapsuleOnDiskLoadPei PEIM will
retrieve the capsules from the relocation temp file and report
capsule hobs for them.
CoDRemoveTempFile() is to remove the relocation temp file in the next
boot after capsules are processed.
