Renames the file to avoid what appears to be automatic inclusion
into the root of the doctree.

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.

The test will always fail on emulated/simulated environments. Exclude
this one which was failing.

7b1a8f4b89 tests: timer: timer_behavior: Fix compile issues
Includes need to be <zephyr/tc_util.h> and <zephyr/ztest.h> otherwise
we get build errors.

fafb4d70b5 kernel: Timer behavioral testing
Test and validate the behavior of a timer driver.

Takes a number of absolute timer cycle samples of a periodic timer then
calculates statistical mean, variance, stddev along with total drift over
the entire test time. Ensures standard deviation and drift are within
a given configurable bound.
