[RFP] `Balancer` pools on the Darwinia

As Uniswap V4 and CowAMM protocols involved, we are updating our requirements, currently looking into Balancer support on Darwinia.

We are looking some friendly forking of Balancer to support our chain instead.

Already shared this idea with some external teams including Helixbox.
