This commit moves the function mpu_configure_regions(.) from
arm_mpu_v7_internal.h to arm_mpu.c. The function is to be used
by the both ARMv7-M MPU driver, as well as the ARMv8-M MPU
driver (when it behaves like the ARMv7-M driver).

We introduce MPU_GAP_FILLING Kconfig option that instructs
the MPU driver to enforce a full SRAM partitioning, when it
programs the dynamic MPU regions (user thread stack, PRIV stack
guard and application memory domains) at context-switch. We
allow this to be configurable, in order to increase the number
of MPU regions available for application memory domain programming.
This option is introduced in arch/Kconfig, as it is expected
to serve as a cross-ARCH symbol. The option can be set by the
user during build configuration.
By not enforcing full partition, we may leave part of kernel
SRAM area covered only by the default ARM memory map. This
is fine for User Mode, since the background ARM map does not
allow nPRIV access at all. The difference is that kernel code
will be able to attempt fetching instructions from kernel SRAM
area without this leading directly to a MemManage exception.
Since this does not compromize User Mode, we make the skipping
of full partitioning the default behavior for the ARMv8-M MPU
driver. The application developer may be able to overwrite this.
In the wake of this change we update the macro definitions in
arm_core_mpu_dev.h that derive the maximum number of MPU regions
for application memory domains.

Adds the model extension concept to the access layer, as described in
the Mesh Profile Specification, Section 2.3.6. Extensions are
implemented as a tree, using two pointers in each model:
The extends pointer points to the first extended model, and the next
pointer points to the next sibling or (if the NEXT_IS_PARENT flag is
set) the parent model in the tree, forming a cyclical "Left-child
right-sibling" (LCRS) tree. The tree root can be obtained by calling
bt_mesh_model_root_get(), and the extended models can be walked by
calling bt_mesh_model_tree_walk().
According to the Mesh Profile Specification Section 4.2.3, all models in
the same extension tree share one subscription list per element. This is
implemented by walking the model's extension tree, and pooling the
subscription lists of all models in the same element into one. If the
config server adds a subscription to a model, it may be stored in any of
the model tree's models' subscription lists. No two models in the same
extension tree and element will have duplicate groups listed. This
allows us to increase extended models' capacity for subscriptions
significantly.

The toolchain_ld_cpp macro currently uses zephyr_ld_options function
to link libstdc++, instead of zephyr_link_libraries which is actually
intended for this purpose.
This commit replaces the usage of zephyr_ld_options with
zephyr_link_libraries as the former may erroneously filter out
-lstdc++ and the latter ensures that this linker flag is
unconditionally forwarded to the linker.
For more details, refer to the issue #20406.

Update Kconfiglib, menuconfig, and guiconfig to upstream revision
faa1d21998, mostly to get this commit in:
Add public helpers for generating "<name> (defined at ...)" strings
Have Symbol/Choice.name_and_loc return strings like
"MY_SYM (defined at foo:1, bar:2)"
"<choice> (defined at foo:4)"
I've added a function like that in at least four different scripts
now, so that's probably a sign that it's a worthwhile helper.
Clean up the tests/Klocation tests a bit while adding tests.
Use the new helper to simplify kconfig.py a bit. Also clean it up a bit
by removing some unused stuff.
Some other minor improvements are included as well, e.g. to make
menuconfig/guiconfig give more helpful errors on invalid arguments.

Add a cleaned-up version of a script I used to find a bunch of unused
symbols and some other Kconfig issues. It's set up to be run directly,
with few environment dependencies.
West is required, because the checks need to see Kconfig files and
source code from all modules.
Checks so far:
- Symbols that can never be anything but n/empty
- Symbols that look unused
- menuconfig symbols with empty menus
- Symbols only defined in Kconfig.defconfig files
See the help strings for the command-line flags for more information.
Some of these checks could probably be checked in CI later, though the
always-n and unused-symbol checks are a bit heuristic and might need a
lot of whitelisting.
Another reason I want to get this in is to have a clean standalone
reference for how to set up the environment for parsing the Kconfig
files. It's gotten trickier over time.
