web-flowMove `QuantumCircuit.assign_parameters` to Rust (#12794) (#12878) * Move `QuantumCircuit.assign_parameters` to Rust This is (as far as I could tell), the last really major performance regression in our asv suite compared to 1.1.0, so with this commit, we should be at _not worse_ for important utility-scale benchmarks. This largely rewrites `ParamTable` (renamed back to `ParameterTable` because I kept getting confused with `Param`) to have more Rust-friendly interfaces available, so that `assign_parameters` can then use them. This represents a 2-3x speedup in `assign_parameters` performance over 1.1.0, when binding simple `Parameter` instances. Approximately 75% of the time is now spent in Python-space `Parameter.assign` and `ParameterExpression.numeric` calls; almost all of this could be removed were we to move `Parameter` and `ParameterExpression` to have their data exposed directly to Rust space. The percentage of time spent in Python space only increases if the expressions to be bound are actual `ParameterExpression`s and not just `Parameter`. Most changes in the test suite are because of the use of internal-only methods that changed with the new `ParameterTable`. The only discrepancy is a bug in `test_pauli_feature_map`, which was trying to assign using a set. * Add unit test of parameter insertion This catches a bug that was present in the parent commit, but this PR fixes. * Update crates/circuit/src/imports.rs * Fix assignment to `AnnotatedOperation` * Rename `CircuitData::num_params` to match normal terminology * Fix typos and :us: * Fix lint (cherry picked from commit a68de4f9f) Co-authored-by: Jake Lishman <jake.lishman@ibm.com>
