Remove @UnstableApi annotation from resolver-* (#9952)

Motivation:

The resolver API and implementations should be considered stable by now so we should not mark these with @UnstableApi

Modifications:

Remove @UnstableApi annotation from API and implementation of resolver

Result:

Make it explicit that the API is considered stable
