refactor: VC, VP, and supporting models moved into components

[Moopli]

• Verifiable Credentials and Presentation models are now in component/models/verifiable
• SD-JWT package is now in component/models/sdjwt
• move jsonld validator to component/models/ld
• Key fingerprint helpers and JOSE extensions moved to component/kmscrypto

All APIs in original afgo pkg/ folders can continue to be used, these now transparently refer/call the moved APIs.
