MdeModulePkg PeiCore: Add PCD to specify PEIM Shadow

Browse Source 
v2 changelog:
Check CurrentPeimHandle to check the matched PeimHandle.
Add check point to ShadowPeiCore based on PCD.

v1 changelog:
PeiCore LoadImage always shadow itself and PEIM on normal boot after
the physical memory is installed. On the emulator platform, the shadow
may be not necessary. To support such usage, new PCD PcdShadowPeimOnBoot
is introduced to specify whether loads PEIM in memory by default.
