Add ERC: Smart Contract Delegation Interfaces

[rojotek]

Adds a new EIP that specifies a delegation interface for smart contract accounts.

This proposal defines interfaces for smart contracts to delegate capabilities to other smart contracts, smart contract accounts, or Externally Owned Accounts (EOAs). The delegating contract MUST implement ERC-1271 along with the IDelegator interface. This framework empowers a delegating contract with the ability to delegate any actions it has the authority to perform, thereby enabling more flexible and scalable contract interactions. This standard outlines the minimal interface necessary to facilitate such delegation.

Additionally, this proposal is compatible with ERC-4337, although its implementation does not necessitate ERC-4337.
