soc: nordic: Add run once and deferred reset configuration

Adds configuration that allows nRF53 and nRF91-based boards to be
flashed through west using sysbuild for multiple images with the
recover or erase options and prevent running those commands for
each image being flash, which would make the device unbootable.
Also defers reset whilst all images for the cores of these SoCs
are flashed.
