Switch to multicall3 for startup

[jshufro]

All the statelessness of rp's multicall logic, but with substantially less requested data.

Startup takes ten seconds:

This is sufficiently fast that we can also stop using the ws event subscription in the go-ethereum library, which has been buggy in the past.

Instead we can RCU a pointer with the multicall results.

Incidentally, this improves the testability of the el abstraction, because we can stop mocking the evm
