Prior to this commit, the `relax::Tuple` constructor left the `struct_info_` field undefined. This is inconsistent with other Relax leaf nodes, such as `relax::PrimValue`, `relax::Constant`, and `relax::ExternFunc`, which initialize their struct info on construction. This commit updates the `relax::Tuple` constructor to define `struct_info_` as `TupleStructInfo`, if all fields have a known struct info. If any field does not have a known struct info, the current behavior is kept, where `struct_info_` is constructed as `NullOpt`, and is later populated by the `relax::BlockBuilder`.
