feat(rust/signed-doc): Use Catalyst ID as KID

[saibatizoku]

Description

Use the catalyst-id and type for it in catalyst-libs, to parse and validate kid for signatures on a signed document.
Implement an authors() function on the document type, which returns a list of all authors (being short_id() versions of all kids. Implement an kids()function on the document type which returns a list of allkids()needed to validate the document. Expose a validate function which takes an algorithm identifier and public key which matches the algorithm, for eachkidreturned by thekids()` function. There is no need to partially validate, so if all public keys are not supplied then validation has failed.

The caller will extract the public key and algorithm from the RBAC registration.
Do not create a new set of types for these, use common types supported and exposed by the RBAC registration crate itself.
