IP address control: don't try to DNS resolve

* This is used when configuring the DNS client, so resolving will not
work
* It is supposed to be a control for entering IPs, not domain names.

Fixes #12464.

Network: added IPAddressControl.

* Based on Adrien's previous work in the DNS settings view.
* The IPv* and DNS add-ons are now using it.
