samples: Fix Wi-Fi and BLE combo radio test for 54H

When a combo radio test is used for 54H, the peripheral radio test uses
the same console as Wi-Fi radio test causing UICR conflicts and failing
to boot both APP and RAD.

Fix the conflicts by adding an overlay that uses defaults.

Fixes SHEL-3287.
