[PATCH V4 15/17] MdeModulePkg: Add a PEIM to install Debug PPI

[Zhichao Gao <zhichao.gao@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1395

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.
