EVM on WASM: EIP-2930 RLP encoding of AccessList

The RLP encoding/decoding is a bit hacky. More precisely the decoding of a list assumes there are essentially no lists inside a list. That is not quite true. In particular EIP-2930 added the notion of access list to transaction (List of access entries to warm up), ignored for the moment. This needs to be addressed at one point once the technology is in place to warm up entries. It does need either using another RLP library or doing a recursive type for RLP decoders.

Note that EIP-1559 transaction come with access list by default.
