samples: smp_svr: extend mcuboot_merged_slot.overlay

The board overlay in bootloader/mcuboot for the
nrf54h20dk/nrf54h20/cpuapp platform is required, but ignored as
FILE_SUFFIX="merged_slot" matches the mcuboot_merged_slot.overlay
in this sample instead.

Copy the missing contents of the board overlay from
bootloader/mcuboot to mcuboot_merged_slot.overlay
