tint: Use type::Struct::Name in CreateASTTypeFor

The declaration may be nullptr, so doing this avoids a potential
nullptr deref when the struct is an internal type (e.g. frexp
result). In these cases we will now fail to resolve the resulting
code, which is a little better than just crashing.

A future change will update the resolver to allow us to use the
internal struct names from our transforms.
