feat: add logic to validate multi proof vc\vp

[skynet2]

VC
According to the spec https://www.w3.org/TR/vc-data-integrity/#proofs, VC can have multiple proofs (Proof Sets), which is currently supported.

Proof Graphs & Chains are more advanced features that are not currently supported by vcs & vc-go.

VP
The spec does not directly mention that the VP should have only 1 Proof because the VP is VC. We will handle it like VC during proof validation.
As we generate options (challenge, domain, etc.) during the OIDC4VP flow, we expect that all proofs will have this option in the presentation.
