refactor(core)!: simplify get creds for proof api (#523)

BREAKING CHANGE: The `ProofsModule.getRequestedCredentialsForProofRequest` expected some low level message objects as input. This is not in line with the public API of the rest of the framework and has been simplified to only require a proof record id and optionally a boolean whether the retrieved credentials should be filtered based on the proof proposal (if available).
