MdeModulePkg/PeiDebugLibDebugPpi: Add PEI debug lib

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

Add a PEI debug library instance PeiDebugLibDebugPpi base on
DebugPpi. Using the combination of the DebugServicePei and
this lib instance can reduce the image size of PEI drivers.

Notes: this library instance can be used only the PEIM
DebugSerivicePei is runed and install the gEdkiiDebugPpiGuid.
And this library contian the depx of gEfiPeiPcdPpiGuid, that
means the PcdPei.inf cannot use this library instance. The
PcdPei.inf should use the same library instance that the
PEIM DebugServicePei consumes.
