Eric Jin c40f7cc7fd FmpDevicePkg: Add Capsule Update Policy Protocol
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1525

* Add Capsule Update Policy Protocol to FmpDevicePkg
* Add CapsuleUpdatePolicyLib instance that uses the services
  of the Capsule Update Policy Protocol
* Add module that produces the Capsule Update Policy
  Protocol using the services of the CapsuleUpdatePolicyLib
  class.
* Update FmpDevicePkg DSC to build the new library instance
  and the new module and update builds of FmpDxe modules
  to demonstrate the use of the different CapsuleUpdatePolicyLib
  instances.
