feat: introduce @auth/firebase-adapter (#7803)

Database adapters are not dependent on Next.js features, so it makes sense to republish them under the `@auth/*` scope.

This PR is part of a series to convert adapters, using `@auth/core` for types.

BREAKING CHANGE:
If you are coming from the previous adapter, change your `package.json`:

```diff
-  "@next-auth/firebase-adapter": "0.0.0",
+  "@auth/firebase-adapter": "0.0.0",
```

And run `npm install`, `yarn install` or `pnpm install` respectively.

**Note:** This packages is published as ESM-only
