Can we introduce a struct for this type, instead of the std::tuple?

It will also help with describing what this complex structure means.

As discussed offline with Ben:
Introducing a struct here requires us to either include the debug-interface.h in
several wasm headers where this information is produced and passed.
We therefore leave it a tuple for now.

We already include debug-interface.h in debug.h and I think it's ok to include
this file in all places where parts of interface implementation are defined.
Tuple requires looking up what each field actually means each time when you see
them in codebase.
