Implement support of the Presentation Request 2.0 protocol in the cloud-agent

[yshyn-iohk]

Problem

Identus Platform doesn't support the Presentation Exchange 2.0

Proposed feature

Presentation Exchange 2.0 is one of the widely used protocols on top of the Present Proof protocol.
It's essential to implement it in the cloud agent to support the well-known protocol between the peers.

Feature description

Required flows:

Holder	Verifier
cloud-agent	cloud-agent
cloud-agent	SDK-TS
cloud-agent	SDK-Swift
cloud-agent	SDK-KMP

Verifier	Holder
cloud-agent	cloud-agent
cloud-agent	SDK-TS

We have prex module to support presentation exchange already when we added oid4vp. Tests are here https://github.com/hyperledger-identus/cloud-agent/blob/main/pollux/prex/src/test/scala/org/hyperledger/identus/pollux/prex/PresentationSubmissionVerificationSpec.scala 😃

Sad story: once we have this, oid4vp move away from presentation exchange 😿
