feat(credential-status): rename plugin interfaces and methods

[mirceanis]

What issue is this PR fixing

fixes #981

What is being changed

I renamed the credential status interfaces to ICredentialStatusVerifier and ICredentialStatusManager and created a ICredentialStatus plugin interface to represent both.
I moved these interfaces to @veramo/core and updated the plugin schema generated.
The schema generation had some issues because of some inline docs so I fixed the inline tsdocs that were creating issues.

There is an extra change in this PR that was not related to #981:
The ICredentialStatusVerifier.checkCredentialStatus method didDoc parameter was renamed to didDocumentOverride and is now optional.
If it is not provided, the IResolver plugin is called to resolve the issuer DID document. I also added a test for this.

Quality

Check all that apply:

• I want these changes to be integrated
• I successfully ran yarn, yarn build, yarn test, yarn test:browser locally.
• I allow my PR to be updated by the reviewers (to speed up the review process).
• I added unit tests.
• I added integration tests.
• I did not add automated tests because _________, and I am aware that a PR without tests will likely get rejected.

Just one issue found related to the revoked field, in the CredentialStatus class, which is still an optional field but in the comments we say it MUST be filled by the implementations.
