MdeModulePkg: Add definitions for EDKII DEBUG PPI

Browse Source 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1549

Add a debug PPI for PEI phase. This PPI will provide basic
services of debug. PEI debug lib instance can use these
services to implement debug function to reduce the PEIMs
which consume the debug lib.
