**Backport:** https://codeberg.org/forgejo/forgejo/pulls/12231 #12202 began a refactor of Forgejo's authentication implementations by providing structured data on an authentication success. However, error cases were maintained as-is in that refactor, leaving a complex situation: what does returning an error from an authentication method mean?; does it mean that the authentication failed, or that a server error occurred? Can another authentication still be tried? This PR changes authentication methods so that they can return one of four things: - `AuthenticationSuccess` with an authentication result. - `AuthenticationNotAttempted` which indicates that no credentials relevant for this authentication method were presented. If every method returned `AuthenticationNotAttempted`, then you would have an unauthenticated access. - `AuthenticationAttemptedIncorrectCredential` which indicates that credentials were present and failed validation -- a situation indicating a `401 Unauthorized`. - `AuthenticationError` which indicates that an internal server error occurred and failed authentication -- indicating a `500 Internal Server Error`. This paves the way for one more refactor coming next: `basic.go` and `oauth2.go` perform 3-4 different authentications each (access tokens, oauth JWTs, actions tokens, actions JWTs, and username/password). With the capability to return these more precise responses, these authentication methods can be split up into separate logic that isn't intertwined together.
