[edk2-devel][PATCH 2/3] MdeModulePkg/CapsuleApp: Enhance CapsuleApp for Fmp Capsule Dependency

["Xu, Wei6" <wei6.xu@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2421

1. Enhance "CapsuleApp -P" to output the depex expression op-codes in
the EFI_FIRMWARE_IMAGE_DESCRIPTOR.
2. Enhance Last Attempt Status String with a new string to describe the
error LAST_ATTEMPT_STATUS_ERROR_UNSATISFIED_DEPENDENCIES.
