Make StarknetTokenBridge EIC2771 compliant

[achab]

This PR aims at making the contract StarknetTokenBridge EIP2771 compliant:

• by inheriting from the contract ERC2771Recipient.sol
• by replacing msg.sender with _msgSender()
• by adding a function to set the trusted forwarder, and another to add recipient version.

We followed this guide from Biconomy to edit the contract.
