efc5fe07a2 kernel: overhaul unused stack measurement
The existing stack_analyze APIs had some problems:

1. Not properly namespaced
2. Accepted the stack object as a parameter, yet the stack object
   does not contain the necessary information to get the associated
   buffer region, the thread object is needed for this
3. Caused a crash on certain platforms that do not allow inspection
   of unused stack space for the currently running thread
4. No user mode access
5. Separately passed in thread name

We deprecate these functions and add a new API
k_thread_stack_space_get() which addresses all of these issues.

A helper API log_stack_usage() also added which resembles
STACK_ANALYZE() in functionality.

Fixes: #17852

8f1780f6de docs: make doxygen happy with new locations
Change @file entry on some headers due to duplicated files in the
include/ tree (real header + shim).
Adapt the doxygen configuration file to the new locations and remove
directories which are already included.

efb8df5366 cleanup: include/: move misc/stack.h to debug/stack.h
move misc/stack.h to debug/stack.h and
create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.
