feat: use halo2curves cycloneMSM

[jonathanpwang]

Optimizing MSM with:

• https://github.com/privacy-scaling-explorations/halo2curves/pull/130
• https://github.com/privacy-scaling-explorations/halo2curves/pull/168
• https://github.com/privacy-scaling-explorations/halo2curves/pull/169

Use halo2curves 0.7.0. This has MSRV 1.74.0 so we bump the nightly version in halo2.
