Extend the device subsystem enumeration script to produce a CMake pre-load script. This allow CMake linker generator scripts to create iterable sections based on output from device subsystem enumeration. This ensures that same functionality is available in both ld linker templates and the linker generator. Update linker generators to support the use of the device subsystem enumeration CMake pre-load script. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>
