[PATCH] MdeModulePkg PiSmmCore: Remove unreferenced symbol for SMRAM profile

[Star Zeng <star.zeng@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=370

Use GLOBAL_REMOVE_IF_UNREFERENCED for some SMRAM profile global variables,
then their symbols could be removed when SMRAM profile is disabled.
