60d03c53e1 libc: minimal: Add 'noreturn' attribute to abort() and exit()
This aligns abort() and exit() definitions with other libc.

Without 'noreturn' attribute, compilers have to assume that we will
return from these functions which can lead to surprising errors like
'error: non-void function does not return a value'.

8eff5b6c01 libC minimal: Fix for POSIX arch
The spin loop in _exit() needs a Z_SPIN_DELAY() for the
posix architecture, so it does not hang the whole
executable on that infinite loop but only the thread
that exit'ed.

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

cbd31d720b lib: migrate includes to <zephyr/...>
In order to bring consistency in-tree, migrate all lib code to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to zephyrproject-rtos#45388 for more details.

af529d1158 libc: minimal: Implement exit()/_exit() functions.
Behavior is similar to newlib version: print "exit" message and go
into infinite loop.
