Draft AZIP to discuss adding L1 block info including storage roots to L2 private and public context.

This AZIP introduces L1 block roots into the Noir contract execution context, enabling trustless reads of L1 state, transactions, and receipts. It outlines the specification for accessing these roots and their implications for various stakeholders.
This AZIP proposal updates the context for accessing L1 block header data in Noir contracts, enhancing the ability to read Ethereum state without oracles. It introduces a new structure for L1 block header fields, optimizing the protocol for trustless reads and reducing gas costs.
Updated the 'discussions-to' field in the AZIP preamble to include a link to the relevant GitHub discussion.
