MdeModulePkg/PiSmmCore: log SMM image start failure

MdeModulePkg/PiSmmCore: log SMM image start failure

In the CoreStartImage() function [MdeModulePkg/Core/Dxe/Image/Image.c], if
the image entry point returns a failure code, then the DXE Core logs a
helpful DEBUG_ERROR message, with the following format string:

  "Error: Image at %11p start failed: %r\n"

Do similarly in the SMM Core (update the message slightly).
