Remove SdkMemberType.FinalizeModule

This was only being used to set the "stl" property for cc library sdk
member type and so that functionality was moved to AddPrebuiltModule()
and FinalizeModule was removed.

Required a few test changes to move the property to the correct
position in the generated module.
