chore: Move authn into cmd/frontend (#63648)
They should not be used outside of cmd/frontend, so making it a frontend
internal package.

While doing that, I realized that there is a coupling dependency between
authz providers and auth (which is authN) providers: GitLab code host
connections can do authz mapping via the usernames of another OIDC or
SAML auth provider
(https://sourcegraph.com/docs/admin/code_hosts/gitlab#administrator-sudo-level-access-token).
It turns out this feature does not work anymore, since at least several
releases, because we don't actually instantiate auth providers outside
of `cmd/frontend` and thus the mapping will never find anything (auth
providers don't explode when queried before init, unlike authz).
This only now became clear as I moved this code, and the dependency
graph was broken, so that's a nice property of these cleanups I guess 😬
Since it doesn't seem to work for quite some time, I opted for removing
it, and added a changelog entry about it. Not sure if that is
sufficient, I raised a thread here:
https://sourcegraph.slack.com/archives/C03K05FCRFH/p1721848436473209.
This would've prevented this change and needed more refactoring as
unfortunately we cannot map an auth provider by the conf type to a
record in the `user_external_accounts` table and need to actually
instantiate it.

Test plan: Compiler doesn't complain, tests still pass.

## Changelog

GitLab code host connections were [able to sync permissions by mapping
Sourcegraph users to GitLab users via the username property of an
external OIDC or SAML
provider](https://sourcegraph.com/docs/admin/code_hosts/gitlab#administrator-sudo-level-access-token)
that is shared across Sourcegraph and GitLab. This integration stopped
working a long time ago, and it has been removed in this release.
