eth-json-rpc-middleware Add eth_getPlumeSignature RPC handler

Context: Implementation of a novel deterministic ECDSA signature scheme in MetaMask https://eprint.iacr.org/2022/1255

Add handler for eth_getPlumeSignature to unblock https://github.com/MetaMask/metamask-extension/pull/17482, as we'd like to use this new RPC method to generate the signature + other necessary SNARK inputs.

We should ensure that the extension team wishes to accept this change before we include it here. Just wanted to give you a heads up before you do more work on these tests, that it might be better to get buy-in from that team first.

Great point! We have already discussed with Alex Bea, Erikson, Kumavis, and Olaf to confirm their buy-in, along with our Metamask grant proposal. Feel free to tag any of them here to confirm!
