Introduce IPGraph Access Control Support

[kingster-will]

Description

This PR introduces IPGraph Access Control (IPGraphACL) support, ensuring that only whitelisted contracts can write to the IPGraph precompiled contract. The IPGraphACL includes a special storage slot that allows whitelisted addresses to set a flag (allow or disallow). The precompiled IPGraph will check this flag for all operations that change the state. The idea is that qualified contracts, like LicenseRegistry, will enable the flag to access the precompiled IPGraph and then disable the flag after writing to the IPGraph.

Key Changes

• IPGraphACL Contract: Added a contract to manage access control for the IPGraph.
• Whitelist Management: Functions to add and remove addresses from the whitelist.
• Flag Management: Functions to set the allow/disallow flag for whitelisted addresses.
• Integration with IPGraph: Ensured that the IPGraph precompiled contract checks the flag before performing state-changing operations.
