Integration with Solday's ERC6551 Implementation

[kingster-will]

Description

Overview

This PR introduces integration with Solday's ERC6551 smart contract. Key modifications include the update of the state variable, renaming it from nonce and changing its type from uint256 to hash (bytes32). This adjustment ensures that state is now deterministic, computed from the input parameters of the execute() function.

Modifications

• Inheritance: IPAccount now extends Solday's ERC6551 contract to utilize its implementation of ERC6551 interfaces including token(), owner(), receiver functions and 1271 signature validation.
• State/nonce Update: Changed the type of state from uint256 to bytes32 according to Solady 6551, which is hash computed based on execute() inputs. All execute functions execute()', executeBatch()andexecuteWithSig()share the function to update 'state' which calculate hash based on common inputs of execute functions:to, valueanddata`.
• Method Overrides: Overrode execute() and executeBatch() methods from Solady ERC6551 to include check permissions via AccessController. This ensures that every execution undergoes a permission verification process.

Test Plan

All new added code covered by automation tests.

LGTM, needs @Vectorized's review

For tests, it'd be better to use parameterized internal functions for repetitive code, e.g. newState and signatures, to improve readability. Pretty hard to scroll through the test cases without getting confused.

Looks good
