Remove code that is only applicable to emitting mscorlib.dll for .NET Framework (#92034)

* Remove code that is only applicable to emitting mscorlib.dll for .NET Framework

These code blocks only apply to compiling/emitting the core library with a GUID (which we only do in .NET Framework) and a custom module name (which we only do in .NET Framework). Additionally, we build SPCL with Roslyn, so even then these code-paths are dead.

* Remove dead GUIDs
