[udp] allow Reference Devices to send UDP messages to TMF port (#6627)
This commit allows Reference Devices to send UDP messages to TMF port,
which was prohibited by #5911 .
Background: TestHarness sends constructed TMF messages in many TCs to
validate the behavior of nodes on receiving these TMF messages.
Fixes DUA-TC-09
