[nrf noup] boot: Configure ROM_END_OFFSET images

Add a possibility to specify, which images should have the
ROM_END_OFFSET automatically adjusted.
Use the UpdateableImages_Get(..) functionality to configure all
updateable images (including radio images as well as variants) in the
default configuration.
