Port `circuit_to_dag` to Rust (#13036)

* Initial: Add add_from_iter method to DAGCircuit
- Introduce a method that adds a chain of `PackedInstruction` continuously avoiding the re-linking of each bit's output-node until the very end of the iterator.
   - TODO: Add handling of vars
- Add header for a `from_iter` function that will create a `DAGCircuit` based on a chain of `PackedInstruction`.

* Fix: leverage new methods in layers
- Fix incorrect re-insertion of last_node.

* Fix: Keep track of Vars for add_from_iter
- Remove `from_iter`

* Fix: Incorrect modification of last nodes in `add_from_iter`.
- Use `entry` api to either modify or insert a value if missing.

* Fix: Cycling edges in when adding vars.
- A bug that adds duplicate edges to vars has been temporarily fixed. However, the root of this problem hasn't been found yet. A proper fix is pending. For now skip those instances.

* Fix: Remove set collecting all nodes to be connected.
- A set collecting all the new nodes to connect with a new node was preventing additional wires to connect to subsequent nodes.

* Fix: Adapt to #13033

* Refactor: `add_from_iter` is now called `extend` to stick with `Rust` nomenclature.

* Fix: Remove duplicate vars check

* Fix: Corrections from code review.
- Use Entry API to modify last nodes in the var.
- Build new_nodes with an allocated vec.
- Add comment explaining the removal of the edge between the output node and its predecessor.

* Fix: Improper use of `Entry API`.
- Use `or_insert_with` instead of `or_insert` to perform actions before inserting a value.

* Initial: Add add_from_iter method to DAGCircuit
- Introduce a method that adds a chain of `PackedInstruction` continuously avoiding the re-linking of each bit's output-node until the very end of the iterator.
   - TODO: Add handling of vars
- Add header for a `from_iter` function that will create a `DAGCircuit` based on a chain of `PackedInstruction`.

* Initial: Expose `CircuitData` interners and ... (continued)
