MdeModulePkg: Add ResetSystemLib instances that call core services
Add a PEI instance of ResetSystemLib that calls the ResetSystem2()
service in the PEI Services Table.
Add a DXE instance of ResetSystemLib that calls the ResetSystem()
service in the UEFI Runtime Services Table.
These 2 library instances should be the default ResetSystemLib
mapping for most PEIMs and DXE drivers so all reset system requests
go through the core service.
Only the implementation of the core servies should use the
platform specific instance of the ResetSystemLib that actually
performs the hardware actions to reset the platform.
