Commit aef50446ce
removed gEdkiiPeiMpServices2PpiGuid from UefiCpuPkg.dec
which causes build breaks if an INF [Ppis] section
lists gEdkiiPeiMpServices2PpiGuid. There is no method
for a DEC file for conditionally declare a PPI.
In order to support the migration from use of
gEdkiiPeiMpServices2PpiGuid to the preferred use of the
gPeiMpServices2Ppi, add gEdkiiPeiMpServices2PpiGuid back
to the UefiCpuPkg.dec.
All references to the EDK II PEI MP Services 2 PPI can be
removed after all downstream consumers have had a chance
to perform the migration.
