Add a specialization of FieldTraits for VariableBlockVector

Summary

This VariableBlockVector has a type field_type but not real_type, it also does not specialize the FieldTraits type-traits class from dune-common. This makes it unusable within a MultiTypeBlockVector, for example. This MR adds the FieldTraits specialization.
