Added EIP7702 stateless and tests

[hanzel98]

What?

• New version of the DeleGator contracts. This contract has been created to be used with EIP7702 Accounts. It deletes the UUPS proxy logic that we used to have in the previous DeleGators. it doesn't modify the previous contracts instead it creates a new core and a new implementation.
• The new implementation is a stateless deleGator that doesn't allow changing the signer/owner of the contract, the only account that can control the smart account is the same EOA where the contracts run. The EOA can interact with the contract via submitting direct transactions to the contract functions, or via the entry point using signatures.

Why?

• The EIP7702 does not require UUPS proxy functionality, because this EIP updates the smart contracts using a different mechanism.

How?

• New set of contracts without touching the previous ones.
• Deleted namespace storage because there is no storage

I like how simple the stateless implementation is.

Very high level review - but LGTM.

One comment on the tests.
