[nrf noup] smp_svr: nrf54h20dk serial sample

Add sample configuration for DFU over UART on
nrf54h20dk_nrf54h20_cpuapp_iron board with MCUBoot support.

Set as no-upstream beacuse of developmental stage of MCUBoot support
on nrf54h20, in particular no functional IPC with secdom and disabled
radio core for the moment.
