Fully port `Depth` and `Size` passes to Rust

[kevinhartman]

Summary

This has a bit of a click-bait title since they're technically already ported (the calls to DAGCircuit::depth and DAGCircuit::size made by the Python passes are already in Rust). But, this PR avoids an isinstance call that was being done for every node in the DAG on calls to these methods when the recurse parameter was specified as true, which should resolve the performance issues we were seeing with these passes.

I've also done this for DAGCircuit::count_ops.
