MdeModulePkg: Add a PEIM to install Debug PPI
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1549 Add a PEIM to install Debug PPI so that PEI debug library instance can locate gEdkiiDebugPpiGuid to implement the debug functions. Using this PPI can reduce the size of PEIMs which consume the debug library.
