Presentation Exchange: support limiting disclosure with ZKP and Selective Disclosure Credentials

[decentralgabe]

Today we do not support building a Presentation Submission if limit_disclosure is set to required. This is because we have no way of detecting whether a credential was signed as a ZKP or SD cred.

The change is to:

1. If limit_disclosure is set to required...
2. Detect if the credential is ZKP or SD
3. See if the claim can fulfill a given input_descriptor
4. If so, construct a limited credential with signature(s) depending on the ZKP/SD scheme
