Add Custom Gates/Instructions in Rust (#15684)

* Initial: Add Custom Gates/Instructions in Rust
- Add `CustomOperation` trait that allows users to implement methods available in both `Instruction`s and `Gate`s.
- Add the packed representation of `CustomOperation` within a `PackedOperation` called `NativeOperation`.
- Use example within `BasisTranslator`'s `compose transforms function where a dummy gate called `CustomDummy` is added to each `DAGCircuit` instance natively.
- Adapt codebase to new additions.

* Fix: Add case for `CustomInstruction` in QPY
- Add missing case for `CustomInstruction` views in QPY.
- Add docstring to `CustomOperation` trait.
- Add miri flag to `try_add_to_circuit`.

* Fix: Add missing methods in `PackedInstruction`.
- Fix formatting and clean up tests.

* Add: `downcast_ref` for `NativeOperation`.
- Add missing docstrings.

* Remove: Gate and Instruction views.
- The following commit removes different views for `Instruction` vs `Gate` in favor of a consolidated view. Users should be able to use `CustomOperation::kind()` to see the type of operation enclosed.

* Add: Method to push custom operation to a Circuit
- Add `CircuitData::push_custom_operation` method to directly push `CustomOperation` instances into a `CircuitData` instance.
- Add `PackedInstruction::from_custom_operation` method to create a full packed instruction directly from a `CustomOperation` implementor.

* Fix: Implement `Deref` and `DerefMut` for `CustomOp`.

* Fix: `Native` -> `Custom`

* Refactor: Hide `CustomOp` to be internal to the `Circuit` crate
The `CustomOp` struct acts as a container to the `Box<dyn CustomOperation>` and its presence outisde of this crate seems to be a little redundant. The following commit reduces the visibility of this struct to only the `circuit` crate, which makes it easier to process a custom operation without the added layer of wrapping it within this struct.

* Docs: Fix `CustomOperation`s docstring

* Revert: Changes to c... (continued)
