How VC/VPs are included in OpenID Connect response

[Sakurann]

Option 1: include vp, vc properties inside an id_token.
pros are id_tokens are already perceived as carrying claims about the user.
cons are this could overload an id_token

Option 2: create a new vp, vc top-level property
pros: clarifies that this is a new credential format
cons: support from RP implementations
