bwatch: add wire format

This wire file primarily contains datastructures that is used to serialize data for storing in the datastore. We have 2 types of datastores for bwatch.
The block history datastore and the watch datastore. For block history we store height, the hash and the hash of the previous block.
For watches we have 4 types of watches - utxo, scriptpubkey, scid and blockdepth watches, each of these have their unique info stored in the datastore. The common info for all watches includes the start block and the list of owners interested in watching.

The short version

What changed, and why it matters

This commit adds a new internal data-format definition (a 'wire format') for a Core Lightning plugin called 'bwatch'. It describes how the plugin will store block history and 'watch' records in its database. There is no executable code in the change—only a build-file update and a CSV file that defines data structures. Nothing in the commit suggests a security vulnerability, fix, or exposure.

Recommended action

No security action required. Review the generated serialization code in follow-up commits to ensure length fields (scriptpubkey_len, num_owners) are validated before use and that datastore reads do not trust malformed records.

Security signals we found

No strong security signals were identified.

contrib: add jaonoctus's signing key
