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.
