Evaluate CONFIG_LINKER_ITERABLE_SUBALIGN in CMake instead of in the
linker script.
It cannot be assumed that a linker generator implementation is
pre-processed and therefore Kconfig settings cannot be used in those
but must be evaluated in CMake.

Introduce core support for ARM's SCMI (System Control and
Management Interface). This includes:
* shared memory (SHMEM) driver. This consists of a suite
of functions used to interact with the shared memory area.
* shared memory and doorbell-based transport layer driver.
Data is passed between platform and agent via shared
memory. Signaling is done using polling (PRE_KERNEL) and
doorbells (POST_KERNEL). This makes use of Zephyr MBOX API
(for signaling purposes) and the SHMEM driver (for polling
and data transfer).
* core driver - acts as glue between transport and protocol
layers. Provides synchronized access to transport layer
channels and channel assignment/initialization.
* infrastructure for creating SCMI protocols
This is based on ARM's SCMI Platform Design Document: DEN0056E.

Remove the deprecated uart_mux and gsm_mux modules and all of
their configurations/dependencies across zephyr.
Optimally uart_mux and gsm_mux would be removed in their own
respective PRs, but the two modules are directly coupled, so
to preserve bisectability, they must be removed together.

USB High-Speed devices must be able to operate at both High-Speed and
Full-Speed. The USB specification allows the device to have different
configurations depending on connection speed. Modify the API to reflect
USB Specification requirements on what can (e.g. configurations) and
what cannot (e.g. VID, PID) be speed dependent.
While the class configurations for different speeds are completely
independent, the actual class instances are shared between operating
speeds (because only one speed can be active at a time). Classes are
free to provide different number of interfaces and/or endpoints for
different speeds. The endpoints are assigned for all operating speeds
during initialization.

Introduce usbd_class_iter for keeping endpoint assignment variables
and the single-linked list node. No functional changes right now, but
this paves the way for independent speed specific configurations.

Add support for mutable devices. Mutable devices are those which
can be modified after declaration, in-place, in kernel mode.
In order for a device to be mutable, the following must be true
* `CONFIG_DEVICE_MUTABLE` must be y-selected
* the Devicetree bindings for the device must include
`mutable.yaml`
* the Devicetree node must include the `zephyr,mutable` property

ZBus stores observers in two ways: statically using a list and dynamically
using a memory slab. Both present limitations. Static observers work only
for channel definition. The dynamic observers rely on a memory slab that
forces the user to manage its size to avoid issues with adding
observers. This commit fixes the static allocation problem by using the
iterable sections for allocating observation data and replacing the VDED
execution sequence since now it is possible to prioritize static observer
execution. All the runtime observers are dynamically allocated on the heap
instead of a specific memory pool.
BREAK changes (only internal, not APIs):
* ZBus channel metadata changed. Remove the observers' static array
pointer. Rename the `runtime_observers` pointer to `observers`. Add
`observer_start_idx` and `observer_end_idx`;
* Change the VDED execution sequence. The position (on definition time),
the priority in conjunction with the lexical order, is considered for
static post-definition time observers. At last, the runtime observer
follows the adding sequence;
* Replace the `CONFIG_ZBUS_RUNTIME_OBSERVERS_POOL_SIZE` with
`CONFIG_ZBUS_RUNTIME_OBSERVERS`.
New APIs:
* New iterable section iterators (for channels and observers) can now
receive a user_data pointer to keep context between the function calls;
* New `ZBUS_LISTENER_DEFINE_WITH_ENABLE(_name, _cb, _enable)` and
`ZBUS_SUBSCRIBER_DEFINE_WITH_ENABLE(_name, _queue_size, enable)` that
enable developers define disabled observers. They need to be enabled
during runtime to receive notifications from the bus;
* `ZBUS_CHAN_ADD_OBS` macro for adding post-definition static observers of
a channel.
Important changes:
* Move the ZBus LD file content to the `common-ram.ld` LD file. That was
necessary to make ZBus compatible with some Xtensa and RISCV boards.

Add support for userspace with RTIO by making rtio and rtio_iodev
k_objects. As well as adding three syscalls for copying in submissions,
copying out completions, and starting tasks with submit.
For the small devices Zephyr typically runs on one of the most important
attributes tends to be low memory usage. To maintain the low footprint of
RTIO and its current executor implementations the rings are not shared with
userspace. Sharing the rings it turns out would require copying submissions
before working with them to avoid TOCTOU issues.
The API could still support shared rings in the future so that a
kernel thread could directly poll, copy, verify, and start the submitted
work. This would require a third executor implementation that maintains its
own copy of submissions similiar to how io_uring in Linux works.

Updates the ztest_test_fail() function to allow failures in setup.
When executed, a failed assert will fail every test in the suite owning
the setup function. This was verified by adding a suite which asserts
in the setup function and has a test that should pass. During
exeuction, ztest marks the test as failing.
In order to verify exection I also added 2 new APIs:
- ZTEST_EXPECT_FAIL(suite_name, test_name)
- ZTEST_EXPECT_SKIP(suite_name, test_name)

The commit dee79d2b66 introduced a new
linker output section ztest_suite_node in linker/common-ram.ld but
without updating the corresponding linker_script/common/common-ram.cmake
linker script generator code.
This causes test cases for arm Compiler 6 to fail.
Add the same section to common-ram.ld.

Converted existing ld script templates into CMake files.
This commit takes the common-ram.ld, common-rom.ld, debug-sections.ld,
and thread-local-storage.ld and creates corresponding CMake files for
the linker script generator.
The CMake files uses the new Zephyr CMake functions:
- zephyr_linker_section()
- zephyr_linker_section_configure()
- zephyr_linker_section_obj_level()
to generate the same linker result as the existing C preprocessor based
scheme.
