_constructorArgsNum is always equal to length (typeArgs _constructorType), I guess? There should be a comment that this field is only a "cache" for this value.

This is fine, but ultimately it would be good to have a (parameterised) transformation on JuvixTree which calculates the representations. It can only be used with the Nockma pipeline until the C code generation supports the representations, but later it could be re-used.

We can represent Anoma types like resource as Juvix records.
The Nockma encoding of types uses Nockma 'tuples' where each component of the tuple holds a value of a field. So for Juvix->Anoma integration it is convenient to compile values of record types as Nockma tuples.
We already have the concept of representing constructors of inductive types that have only one non-zero-field constructor in the compiler, see
MemRepTuple.In this PR, as part of the Nockma step, we mark constructors that satisfy the requirements of the
MemRepTupletranslation as such. Then we use a tuple encoding for those constructors.
