remove `claims` parameter from ISO mdoc and SD-JWT VC Credential Request

[paulbastian]

Partly solves #151

Remove the claimsparameter from Credential Request for Credential Formats that support selective Disclosure anyway as this:

• is a potential privacy leak to the Credential Issuer
• hinders interoperability when users have a Credential with subset of claims in their wallet and other Verifiers want other claims (which will be unexplainable to the user)
• this has been an interop issues in LSP hackathon as particpants interpreted this differently
