chore(storage): tcp and udp fields for all servers

- Updater code sets UDP and TCP compatibility for all providers
- Increase servers.json model versions for affected providers (mullvad, windscribe, privado, protonvpn, privatevpn)
- Remove retro-compatibility server defaults
- Update all affected providers servers data (mullvad, windscribe, privado, protonvpn, privatevpn)
