Cleanup INF file for PEI Core

Cleanup INF file for PEI Core
1) Remove references to CPU I/O PPI and PCI CFG2 PPI.  The PEI Core does have the PEI Services Table that caches a copy of these, but the PEI Core never produces a real version of these PPIs.  Instead, the PEI Core only has a null implementation of the APIs so we can catch PIEMs that call these services before they are properly installed.
