Core/Channel: revamp channel system (#17980)

* Core/Channel: change the way channels are stored and sent to client.

- Fixes multiple channels per zone when using different locales
- Connected clients will receive locally the name of the channel for their apropiate locale (if available)
- In other cases default locale name will be sent, so as to prevent breaking channel chat for those players

Closes #8411
