Subject: UefiCpuPkg: Add PlatformSecLib

Add PlatformSecLib class and PlatformSecLibNull instance
that is used by the SecCore.  PlatformSecLibNull should
not be used in a platform build.  Instead, it should be
used as a template for implementing a platform specific
instance of the PlatformSecLib library class.
