EIP-7702 Support

[dancoombs]

Describe the feature
Add support for EIP-7702 .

Likely set of changes:

• Modify RPC types to accept a 7702 authorization tuple alongside a user operation. The exact shape of this RPC should be agreed upon by other bundler providers.
• Modify preVerificationGas estimation and requirements to correctly charge for a EIP-7702 transaction.
• Use state overrides to set the account code while estimating gas, simulating the UOs, checking the bundle, etc.
• Hold onto the authorization tuple in the mempool alongside the UO.
• Send 7702 transactions in the bundler if any UO contains a authorization tuple.

The reference bundler currently has a branch with 7702 support: https://github.com/eth-infinitism/bundler/tree/AA-453-eip-7702-support
