b417442575 doc: kernel: document general policy for Zephyr without threads
This provides the documentation of scope required as a stage towards
removing deprecation for CONFIG_MULTITHREADING=n.  The specific lists
of what does work will follow as the code base is inspected and
updated.

6965cf526d kernel: Deprecate k_mem_pool APIs
Mark all k_mem_pool APIs deprecated for future code.  Remaining
internal usage now uses equivalent "z_mem_pool" symbols instead.

Fixes #24358

262bf14c63 doc: kernel: add section about queues
We did not have any reference to queues and doxygen information were not
linked correctly. Add a placeholder and pull in doxygen data so whenever
someone adds a reference, a link is created.

fadd98aad2 sys: add generic asynchronous notification infrastructure
k_poll() for a signal is often desired for notification of completion
of asynchronous operations, but there are APIs where it may be
necessary to invoke "asynchronous" operations from contexts where
sleep is disallowed, or before the kernel has been initialized.
Extract the general notification solution from the on-off service into
a utility that can be used for other APIs.

Also move documentation out to a resource management section.

1964bf08bb lib: os: onoff: add API for on-off service request and release management
There are various situations where it's necessary to support turning
devices on or off at runtime, includin power rails, clocks, other
peripherals, and binary device power management.  The complexity of
properly managing multiple consumers of a device in a multithreaded
system suggests that a shared implementation is desirable.  This
commit provides an API that supports managing on-off resources.

d803a534c0 docs: kernel: thread documentation enhancements and cleanup
Moving all thread docs into 1 page was a bit too much. Split the section
a bit and remove redundant and useless sections and move some thread
related documentation from the scheduling page to threads (thread states
and priorities).

Add a new figure for thread states.

4ce988ab43 doc: provide error handling documentation
We don't really have docs on how fatal errors are induced
or handled. Provide some documentation that covers:

- Assertions (runtime and build)
- Kernel panic and oops conditions
- Stack overflows
- Other exceptions
- Exception handling policy
