feat(core): actor token

[wangsijie]

Summary

Implement "actor token" feature in token exchange according to the RFC.

If actor_token is present, will add an extra claim act to the response access token.

Because the class AccessToken can only accept a list of predefined claims, so we have to set the act claim to extra first, and then extract it to the outside in extraTokenClaims option of node-oidc-provider.

This PR also includes the refactor of token-exchange.ts, it is now splited into a folder of files.

Testing

Unit and integration tests.
