FmpDevicePkg: Add FmpDependencyCheck library class and instances

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2696

* This library class provides platform specific services to support
dependency check during updating firmware image. Platform can perform
dependency check in platform specific manner by implementing its own
FmpDependencyCheckLib.
* Add FmpDependencyCheck instance to provide a sample of dependency
check. The sample instance only checks the dependency from capsule
image. The dependency from other FMP instances isn't checked here.
* Add NULL instance as an option to skip the dependency check.
