zephyr: Add support for image ROM address verification

The commit adds IMAGE_F_ROM_FIXED_ADDR flag that allows to use
ih_load_addr to identify the flash address the image is intendant to
start at.
The code, that supports this flag, will reject image before attempting
flash write if slot address differs from the base address of the image.
The feature can be used to mark Direct-XIP images with slot address
they are intended for.
The CONFIG_IMG_MGMT_REJECT_DIRECT_XIP_MISMATCHED_SLOT has been added
to turn the featre on.
