Jordan Yates 28b2e55321 cmake: rework linker script generation and linker prebuilt stages This commit reworks the linker script generation and linking stages in order to better support fixed section location as required by #38836. Today we have the following generated linker scripts and the elf output depending on the system configuration: - linker_app_smem_unaligned.cmd --> app_smem_unaligned_prebuilt.elf - linker_zephyr_prebuilt.cmd --> zephyr_prebuilt.elf - linker.cmd --> zephyr.elf as not all linker scripts may be created and as there is a need for the possibility to move gen handles earlier then those stages has been renamed into more generic names so that with this commit we have: - linker_zephyr_pre0.cmd --> zephyr_pre0.elf - linker_zephyr_pre1.cmd --> zephyr_pre1.elf - linker.cmd --> zephyr.elf This also means that is the stage zephyr_pre1 is not needed, then build can go from `zephyr_pre0.elf` to `zephyr.elf`. The gen_handles.py has been changed so it now uses `zephyr_pre0.elf` as input. This ensures that the handles array are final when invoking the next build and linking stages. To keep the current behavior of generating the isr table and kobj hash of what was `zephyr_prebuilt` stage the code blocks contolling isr generation and kobj hash has been relocated to be located after app_smem and device handle generation.

Jordan Yates 28b2e55321 cmake: rework linker script generation and linker prebuilt stages

This commit reworks the linker script generation and linking stages in
order to better support fixed section location as required by #38836.

Today we have the following generated linker scripts and the elf output
depending on the system configuration:
- linker_app_smem_unaligned.cmd --> app_smem_unaligned_prebuilt.elf
- linker_zephyr_prebuilt.cmd    --> zephyr_prebuilt.elf
- linker.cmd                    --> zephyr.elf

as not all linker scripts may be created and as there is a need for the
possibility to move gen handles earlier then those stages has been
renamed into more generic names so that with this commit we have:
- linker_zephyr_pre0.cmd --> zephyr_pre0.elf
- linker_zephyr_pre1.cmd --> zephyr_pre1.elf
- linker.cmd             --> zephyr.elf

This also means that is the stage zephyr_pre1 is not needed, then build
can go from `zephyr_pre0.elf` to `zephyr.elf`.

The gen_handles.py has been changed so it now uses `zephyr_pre0.elf` as
input. This ensures that the handles array are final when invoking the
next build and linking stages.

To keep the current behavior of generating the isr table and kobj hash
of what was `zephyr_prebuilt` stage the code blocks contolling isr
generation and kobj hash has been relocated to be located after
app_smem and device handle generation.
