[PATCH] MdeModulePkg DxeCore: Remove unreferenced symbol for memory profile

[PATCH] MdeModulePkg DxeCore: Remove unreferenced symbol for memory profile

[Star Zeng]

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

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