Optimize recursive Poseidon constraint evaluation (#333)
* More wires for ConstantGate

* fix

* fix

* Optimize recursive Poseidon constraint evaluation

- Avoid `ArithmeticGate`s with unique constants; use `ConstantGate` wires instead
- Avoid an unnecessary squaring in exponentiations

Brings Poseidon evaluation down to a reasonable 273 gates when `num_routed_wires = 48`.

PoseidonMdsGate (#330)
PoseidonGate's recursive evaluations were using a lot of gates, and the MDS layer was the main culprit.

The other issue is that `constant_layer_recursive` creates a bunch of `ArithmeticGate`s with unique constants. We could either change `ArithmeticGate` to support different constants per operation, or wire in constants from `ConstantGate`, and change `ConstantGate` to support several constants per gate.

This won't really help anything near term since we're still between 2^12 and 2^13, but could have some benefits later, depending on what recursion arities and security settings we end up using.

`PoseidonMdsGate` needs `2 * D * WIDTH = 48` routed wires, and the combination of adding a gate and increasing routed wires slows down the prover a bit. So for now, I kept it at 28 wires, and the old code path is still used.

2 challenges, 28 routed wires (#310)
* 2 challenges, 28 routed wires

2 challenges gives certain checks approximately (field_bits - degree_bits) * 2 bits of security, so we maintain our target of 100 bits for circuits with 2^14 gates or fewer.

28 routed wires is the min for `InterpolationGate`. A lower number helps reduce proof sizes. We can go back to a high number if there's any strong reason to reduce our gate count (e.g. if we were trying to hit 2^12).

* Check FRI conjectured security

* Fix
