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...

Add methods for the linker-script generator to pick up information
from previus linkerpasses:
* zephyr_linker_include_generated(FILE f.cmake [PASS X] [KCONFIG])
cmake-includes f.cmake in the relevant PASSes. This allows scripts
to generate any content (e.g. sections or section configs) as if
it was generated by the main cmake machiery. This is intended to
cover the case of ld-script snippets generated by e.g.
gen_app_partitions.py
It can also parse KCconfig files to capture @CONFIG_FOO@ variables
* @FOO[,undef:v]@ in an value or expression in the zephyr_linker_*
inputs. This looks for a defintion of FOO (se below), and uses its
value if found. If FOO is not defined, the whole @@ thing is left
untouched, unless ,undef: is used, in which case v is used instead.
* zephyr_linker_include_generated(FILE f.h [PASS x]) greps for f.h
for #define FOO value to be accessed as @FOO@
* zephyr_linker_include_var(VAR FOO VALUE V) allows the main
cmake-script to set a @FOO@ variable.
Note that the #define support is VERY basic, and does not use a proper
pre-processor. It works for the current use of files generated by e.g.
gen_kobject_placeholders.py but is not a general solution.

Extend `zephyr_library_amend()` to support an optional directory
argument.
The current `zephyr_library_amend()` works well when used inside a
Zephyr module with same structure, but fails when the macro is called
from Zephyr module integration code is located in a Zephyr
`MODULE_EXT_ROOT` because in this case the CMake code being executed
is not present in the Zephyr module itself, in which case the dir name
creation based on relative to module dir give wrong result.
For this use-case then support a base directory.
This also allows for use-cases in Zephyr modules where the directory
structure matching Zephyr's own structure is placed in a sub-folder.

In the linker script generator there was one error checking

Recently 0ae0c3dc44 allowed for three digit priorities, this resulted
in objects potentially matching multiple sections, for example:
.z_init_PRE_KERNEL_2_0_0_
.z_init_PRE_KERNEL_2_?_*
.z_init_PRE_KERNEL_2_???_*
This does not seem to be detected by ld, but the IAR linker emits a
warning.
Add some extra qualifiers in the object section name to make it
unambiguous, this has the extra value of making it easier to interpret,
for example going from:
.z_init_POST_KERNEL_90_00012_
to
.z_init_POST_KERNEL_P_90_SUB_00012_

On RISC-V, GCC and possibly other compilers include small globals in
special "small data" sections like .sbss and .sdata.
This allows accessing these globals using the global pointer register
and an offset, which is faster than ordinary relocations.
Currently, llext_load does not support multiple NOBIT sections.
Thus, llext's that use both .bss and .sbss sections cannot be relocated.
Also, the global pointer cannot be used in llext's, as it does not
change when calling into or returning from an llext, making the
optimization pointless for llext.
This commit disables the use of small data sections by adding the
appropriate compiler flag when compiling llext's.
In addition to solving the aforementioned issue, this fixes llext's
test_inspect on RISC-V.

One might want to select the symbols to be relocated inside a file or
