Add westend system chains as a trusted teleporters (#7787)

Asset Hub Next has been deployed on Westend as parachain 1100, but it's
not yet a trusted teleporter.
This minimal PR adds it in stable2412 so that it can be deployed right
away without waiting for the rest of the release to be finalised and
deployed.
