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.

Old tests/kernel/sched/preempt cannot be run repeatedly.
If you register the test_preempt() method twice, the
second run will fail. It is because the participating
threads don't exit properly when the main thread exits.
The new ztest fx implies that a unit test should be able
to run repeatedly. This commit enables that for the preempt
test by adding explicit epilogue.

When test tests/kernel/sched/schedule_api, it shows "ASSERTION FAIL:
timeslice in ticks much be divisible by two", then break and fail
the test.
Fixes#44887.
On board it8xxx2_evb, it can pass schedule_api test without
the assertion, so I add the floating part back to half_slice_cyc
when the timeslice in ticks can't be divisible by two.
After change, the time slice will be:
1.slice_ticks = (200x8192+999)/1000 = 1639 (not changed)
2.before add the deviation (not handle the floating part):
half_slice_cyc = (1639/2) * (32768/8192) = (819) * (32768/8192) = 3276,
after add the deviation:
half_slice_cyc = 3276 + (32768/8192/2) = 3278,
and it's equal (1639/2) * (32768/8192) = 3278.

This commit adds an additional test case for several kernel test suites
to ensure that the linker script generator is working correctly for a
subset of the Zephyr test suites.
The ensures that the basic functionality of the linker script generator
is working while still keep the performance impact on CI at a minimal
level.
Using the kernel tests is a trade-off between testing coverage of the
linker script generator and the time it takes to complete CI.
The kernel tests is considered to have the broadest coverage of various
features important for the generated linker script.

The main reason for increasing CMake version is better toolchain

The stack array tstacks was declared in the header file using
the same macro which defines the same stack array but with
an added "extern" in front. This macro adds alignment and section
attribute which are actually not the same as the actual stack array
defined in main.c. The section name used in the section attribute
contains the file name where the stack array is defined or extern
declared. So the same symbol, in this case z_interrupt_stacks, has
different attributes in two places, and GCC 11 starts to complain
about this. So use the newly introduced macro to extern declare
the stack array without adding/replacing any symbol attributes.

When calculating the expected interval for threads other than
the first one, the test uses ms->ticks->cycles conversion to
figure out the bound of cycles permitted. Both lower and upper
bound conversions are using the k_*_to_*_floor32(). When
numbers involved are not wholly divisible, decimal points are
being truncated, resulting in incorrect intervals, and thus
failing tests. So change the calculation to appropriate
floor() or ceil() based on the boundary.

The deadline scheduler as of commit ef626571b2 ("kernel/sched:
Optimize deadline comparison") got an optimization that requires that
the the cycle difference of the deadline time of the "first" and
"last" runnable thread never be higher than 2^31.
The test code here was masking off the bottom 31 bits of the generated
deadlines, so it looked OK. But because the actual setting of the
deadline values takes time too, it was still possible to select values
that would roll over. The window was VERY small, but the RNG on one
platform (up_squared) hit it.
Shrink the selected deadlines to live in a 30 bit space for safety.
