sample: dfu: smp_svr: add nrf7120-ns support to smpsvr sample

Add nrf7120-ns tfm-mcuboot integrated sample to smpsvr, the overlay file
added in smp_svr contains full flash layout for a MCUBoot sample
integrated with tfm.

Where flash layout is includes boot partition, slot0, slot1, secure
storage, non-secure storage. Slot 1 ad non secure storage are set as
non secure.
