Support Lens (cowprotocol#3469)

# Description
This PR contains changes that are required to run the protocol on the
Lens chain.

# Changes

- All the SCs available on this chain from the existing list.
- Since balancer vault is not available on Lens, I dropped it and some
others from the baseline config since they were unused anyway.
- Migrate to UniswapV3SwapRouterV2.

## How to test
Run locally with the baseline solver:
- [x] Sell order quoting works
- [x] Buy order quoting works
- [x] Placing sell order works
- [x] Placing buy order works
