Create IndyVdrAnonCredsRegistry without revocation

[TimoGlastra]

Create an IndyVdrAnonCredsRegistry that implements the AnonCredsRegistry interface from the @aries-framework/anoncreds package using the indy vdr library.

• Implement the AnonCredsRegistry interface methods from the anoncreds package.
  • read/write schema
  • read/write credential definition
  • return not implemented error for revocation status list and revocation registry definition
  • add tests
  • should be added to the @aries-framework/indy-vdr package
• Utils present in the indy-sdk package that are needed, can be copied to the indy-vdr package.
• The overall structure can stay the same (responses etc..), but we should update it to use the IndyVdrPoolService
• The indyVdrPoolService can be injected using agentContext.dependencyManager.resolve(IndyVdrPoolService)

Resources

• Specification: https://hyperledger.github.io/anoncreds-spec/
• https://hyperledger.github.io/indy-did-method/#other-indy-ledger-object-identifiers
• https://www.hyperledger.org/blog/2022/11/15/announcing-hyperledger-anoncreds-open-source-open-specification-privacy-preserving-verifiable-credentials

Can use the IndySdkAnonCredsRegistry as an example, but must be updated to use the IndyVdrPoolService and IndyVdrPool.

We may need to transform the structure of some objects. As the AnonCreds interfaces are different than what is stored on the indy ledger. However, the same transformations are present in the IndySdkAnonCredsRegistry class, so should make sure it is correct, but we can mostly copy the transformations from the existing implementaiton.
