MdeModulePkg/NvmExpressPei: Add logic to produce SSC PPI
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1409
For the NvmExpressPei driver, this commit will add codes to produce the
Storage Security Command PPI if the underlying NVM Express controller
supports the Security Send and Security Receive commands.
