Sends a message to the Gateway contract to create a new channel representing origin

Fee required: Yes

This extrinsic is permissionless, so a fee is charged to prevent spamming and pay for execution costs on the remote side.

The message is sent over the bridge on BridgeHub's own channel to the Gateway.
