Port QuantumCircuit.count_ops() to rust

[mtreinish]

What should we add?

Right now the QuantumCircuit.count_ops() method is written in Python by iterating over the circuit data and collecting counts in a dictionary, sorting it by gate name and returning that dictionary. However, the underlying data is stored in rust's CircuitData struct and it would be much more efficient to do the counting and in rust. We should port this utility method to rust to provide and provide a significant speedup for the method.
