feat: make VP request to CredentialService

[paullatzelsperger]

What this PR changes/adds

This PR adds the DefaultCredentialServiceClient, which is used to make VP requests against a CredentialService to obtain VPs.

In addition, this PR adds a JwtToVerifiableCredentialTransformer and a JwtToVerifiablePresentationTransformer, as they didn't exist up until now.

Why it does that

IATP implementation

Further notes

• Currently, sending DIF Presentation Definitions is not yet supported. So we need to parse whatever is coming back from the CS.
