Based on content from the following branch:

https://github.com/Microsoft/MS_UEFI/tree/share/MsCapsuleSupport/MsCapsuleUpdatePkg

Add library instances for FmpDeviceLib, CapsuleUpdatePolicyLib,
and FmpPayloadHeaderLib.

Library Classes
===============
* FmpDeviceLibNull - Non-functional template of the FmpDeviceLib
  that can be used as a starting point for an FmpDeviceLib for
  a specific firmware storage device.
* CapsuleUpdatePolicyLibNull - Functional template of the
  CapsuleUpdatePolicyLib that can be used as a starting point
  of a platform specific implementation.
* FmpPayloadHeaderLibV1 - Version 1 of the FmpPayloadHeaderLib.
  This library is indented to be used "as is" with no need for
  any device specific or platform specific changes.
