Add EVM-compatible JSON RPC wrapper to Paima

[SebastienGllmt]

With this change, you can now query the current block number of a Paima rollup using EVM JSON RPC queries

curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' http://localhost:3333/rpc/evm

I've only implemented a few of the endpoints (some of them can't be implemented), but hopefully we can implement the few required to improve interoperability of Paima-based apps with existing tools

In the same PR, I also introduced a new typed getPaimaNodeRestClient so you can call @paima/rest endpoints with automatically generated type definitions instead of having to manually copy the types in the middleware everytime

TODO

• verify params actually match the types
• InternalRpcError swallows the internal error which makes it not show up anywhere. It seems internal errors need a specific shape to work (see RpcError)
• Fix the generated error types for @paima/rest
