Deprecate `vc` & `vp` ?

[OR13]

These are registered claims at:

• https://www.iana.org/assignments/jwt/jwt.xhtml

As it says, the change controller is IESG, but it references v1.0 of the data model, specifically:

• https://www.w3.org/TR/2019/REC-vc-data-model-20191119/

In v2, we removed these from the core data model, and we removed them from this specification.

Should we tell the IESG to update the registry in any way?

VCDM 2.0 charter clearly states "It will replace the current Verifiable Credentials Data Model 1.1 Recommendation." so the best thing is probably to deprecate these claims.

though in reality i would expect VCDM 1.1 implementations to remain in the wild so not sure what impact this deprecation will have on them. (cc: @bc-pi)

deprecation should not break any existing JWT implementations... JSON ignores fields it does not understand.
