all: add support for EIP-2718, EIP-2930 transactions (#21502) This adds support for EIP-2718 typed transactions as well as EIP-2930 access list transactions (tx type 1). These EIPs are scheduled for the Berlin fork. There very few changes to existing APIs in core/types, and several new APIs to deal with access list transactions. In particular, there are two new constructor functions for transactions: types.NewTx and types.SignNewTx. Since the canonical encoding of typed transactions is not RLP-compatible, Transaction now has new methods for encoding and decoding: MarshalBinary and UnmarshalBinary. The existing EIP-155 signer does not support the new transaction types. All code dealing with transaction signatures should be updated to use the newer EIP-2930 signer. To make this easier for future updates, we have added new constructor functions for types.Signer: types.LatestSigner and types.LatestSignerForChainID. This change also adds support for the YoloV3 testnet.
