To: devel; +Cc: Michael D Kinney, Liming Gao, Sean Brogan
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2696
* This library class provides services to check Fmp Capsule Dependency
during updating firmware image, save the dependency to Fmp device after
update succeed and retrieve the dependency from Fmp device.
* Add FmpDependencyCheck instance, and provide PCD as an option to
disable Fmp Capsule dependency feature support.
* Add NULL instance as an option to skip the dependency check.

To: devel; +Cc: Michael D Kinney, Liming Gao, Sean Brogan
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2696
Remove the orginal Fmp Capsule Dependency implement, and use new
FmpDependencyLib and FmpDependencyCheckLib APIs instead. A platform
can perform the dependency check in a platform specific manner by
implementing its own FmpDependencyCheckLib.

> This patch series move the implementation of Fmp Capsule Dependency from
> FmpDxe driver into two library classes. FmpDependencyLib is a base lib
> to provide generic dependency evaluation services. FmpDependencyCheckLib
> is a platform lib to provide dependency check services during firmware
> update. Platform can perform the dependency check in platform specific
> manner by implementing its own FmpDependencyCheckLib.
> This patch series also add unit test for EvaluateDependency API in
> FmpDependencyLib.
