All in all this makes cmake linker generator able to work for at least
most of the kernel tests and samples, on cortex m4.
Make the cmake linker generator have a file-structure more similar to
the ld-skeletons.
Add or edit groups, sections and logic to make the generator reflect
what the ld-skeletons do, esp. for kobjects and APP_SMEM, nonint and
some other details are also effected.
Use the new zephyr_linker_include_generated() and
zephyr_linker_include_var() functions to to handle
${DEVICE_API_LINKER_SECTIONS_CMAKE}, the kobject-prebuilt-*.h files and
APP_SMEM partition. Essentially the output from gen_app_partitions.py,
gen_kobject_placeholders.py.
Add ALIGN_WITH_INPUT on sections being put into DATA_REGION. This makes
the init layout work for ld.
This leverages the updates in gen_app_partitions.py to generate its
output as cmake linker generator sections too, and puts them into a
group defined in linker.cmake
Setup generator variables for alignment of APP_SMEM. Note that this does
not yet handle MPU_ALIGN which depends on the size of the section...
Fix broken k_object_assignment iterable section
