d51a67b7c0 cmake: support ELF image adjustment
This commit adds support for adjust the addresses of the final image.
This is useful when the image is to be flashed at a location different
from the LMA address encoded in the ELF file by the linker.

An example use-case is multicore systems where core A might load image
from a flash partition into RAM in order for core B to execute and load,
but where the image itself is build with the RAM addresses as LMA.

It updates the zephyr_image_info.h header with information of adjustment
value.

c8ddc34bb8 scripts: generate image info header file
This commit adds the `gen_image_info.py` script which supports creation
of a header file with image information from the EFL file.

This version populates the header file with:
- Number of segments in the image
- LMA address of each segment
- VMA address of each segment
- Size of each segment

The header file can be used by a secondary build system which needs this
information.
