Functionality to list operations in QuantumCircuit with associated Qubits

[tonmoy-b]

fixes #12972

Summary

Added function to tally operations in circuit with associated qubits fixes #12972

Details and comments

-Added function count_ops_with_qubits() in quantumcircuit.py, this returns the operations in the QuantumCircuit along with the qubits associated with those operations. -The abovementioned function uses the Rust function fn operations_with_qubits in circuit_data.rs -A test (test_count_ops_with_qubits()) has been added to file test/python/circuit/test_circuit_data.py -tox has been run -- no test failures reported -tox -eblack run to reformat files

Hi @mtreinish ,

 I have made this PR to fix issue 12972: Add a method to compute gate counts per qubit 
 
 Kindly take a look and let me know if any changes should be made.

 For a quick look, the new code works as below:
 a = QuantumCircuit(3, 3)
    a.h(0)
    a.x(1)
    a.h(1)
    a.cx(1, 0)
    b = a.count_ops_with_qubits()
    assert b == [
        ("h", "Qubit(QuantumRegister(3, 'q'), 0)"),
        ("x", "Qubit(QuantumRegister(3, 'q'), 1)"),
        ("h", "Qubit(QuantumRegister(3, 'q'), 1)"),
        ("cx", "Qubit(QuantumRegister(3, 'q'), 1)"),
        ("cx", "Qubit(QuantumRegister(3, 'q'), 0)"),
    ]

Hi, I don't mean to be a nuisance but I would appreciate a review and suggestions for updates if needed. Thanks

Hi, I'd appreciate a review of this PR. I believe it is probably close to what's required at this point.
