The gen_kobject_list.py script looks at DWARF debug information in the
elf file to determine the address of variables. Make sure that when
looking at DW_FORM_exprloc, it looks at both DW_OP_addr and
DW_OP_plus_uconst.

Add a new async API based on the RTIO subsystem. This new API allows:
1. Users to create sampling configs (telling the sensor which channels
they want to sample together).
2. Sample data in an asynchronous manner which provides greater control
over the data processing priority.
3. Fully backwards compatible API with no driver changes needed for
functionality (they are needed to improve performance).
4. Helper functions for processing loop.

Disables allowing the python argparse library from automatically
shortening command line arguments, this prevents issues whereby
a new command is added and code that wrongly uses the shortened
command of an existing argument which is the same as the new
command being added will silently change script behaviour.

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.

In some circumstances, _thread_idx_map[] is all zero and the linker
decides to put it into BSS instead of DATA section. This results in
kernel objects being pushed away so the hash table is no longer
valid. This forces _thread_idx_map to be in the data section inside
the intermediate object file so it will be placed in the data
section in final binary.

Threads may wait on an event object such that any events posted to

This allows memory partitions to be put into the pinned
section so they are available during boot. For example,
the stack guard (in libc partition) is needed during boot
but before the paging mechanism is initialized. Without
pinning it in physical memory, it would fault in early
boot process.
A new cmake property app_smem,pinned_partitions is
introduced so that additional partitions can be pinned
if needed.

The k_object API associates mutable state structures with known kernel
objects to support userspace. The kernel objects themselves are not
modified by the API, and in some cases (e.g. device structures) may be
const-qualified. Update the API so that pointers to these const
kernel objects can be passed without casting away the const qualifier.

These stacks are appropriate for threads that run purely in
supervisor mode, and also as stacks for interrupt and exception
handling.
Two new arch defines are introduced:
- ARCH_KERNEL_STACK_GUARD_SIZE
- ARCH_KERNEL_STACK_OBJ_ALIGN
New public declaration macros:
- K_KERNEL_STACK_RESERVED
- K_KERNEL_STACK_EXTERN
- K_KERNEL_STACK_DEFINE
- K_KERNEL_STACK_ARRAY_DEFINE
- K_KERNEL_STACK_MEMBER
- K_KERNEL_STACK_SIZEOF
If user mode is not enabled, K_KERNEL_STACK_* and K_THREAD_STACK_*
are equivalent.
Separately generated privilege elevation stacks are now declared
like kernel stacks, removing the need for K_PRIVILEGE_STACK_ALIGN.
