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.

c7b5b3c419 samples: migrate includes to contain <zephyr/...> prefix
In order to bring consistency in-tree, migrate all samples to the use
the new prefix <zephyr/...>. Note that the conversion has been scripted:

```python
from pathlib import Path

EXTENSIONS = ("c", "h", "cpp", "rst")

for p in Path(".").glob("samples/**/*"):
    if not p.is_file() or p.suffix and p.suffix[1:] not in EXTENSIONS:
        continue

    content = ""
    with open(p) as f:
        for line in f:
            m = re.match(r"^(.*)#include <(.*)>(.*)$", line)
            if (m and
                not m.group(2).startswith("zephyr/") and
                (Path(".") / "include" / "zephyr" / m.group(2)).exists()):
                content += (
                    m.group(1) +
                    "#include <zephyr/" + m.group(2) +">" +
                    m.group(3) + "\n"
                )
            else:
                content += line

    with open(p, "w") as f:
        f.write(content)

Now that device_api attribute is unmodified at runtime, as well as all

5be0d00d41 treewide: remove unnecessary DT GPIO/PWM flags checks
Now that the relevant APIs generalize properly for bindings without
flags, we can remove some special case checks from the tree.

I couldn't find any more, but I did this kind of quickly, so it's
possible I missed some.

c58db0c995 samples: threads: cleanups
Align the docs and source code with other changes done to the basic
samples.

Use numbers 0 and 1 to refer to the LEDs consistently. This matches
the generic devicetree aliases used by Zephyr, instead of using USR1
and USR2, which are specific to 96b_carbon.

32bb2395c2 timeout: Fix up API usage
Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them.  Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:

+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
  values for equality (e.g. with K_FOREVER or K_NO_WAIT).

+ Adding a k_msleep() synonym for k_sleep() which can continue to take
  integral arguments as k_sleep() moves away to timeout arguments.

+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
  generate timeout arguments.

+ Removing the usage of K_NO_WAIT as the final argument to
  K_THREAD_DEFINE().  This is just a count of milliseconds and we need
  to use a zero.

This patch include no logic changes and should not affect generated
code at all.

830b8bdc17 samples: threads: Rewrite misleading sample
The basic/threads sample is printing a log that looks like this:

Toggle USR0 LED: Counter = 0
Toggle USR1 LED: Counter = 0
Toggle USR0 LED: Counter = 1
Toggle USR0 LED: Counter = 2
Toggle USR0 LED: Counter = 3
Toggle USR0 LED: Counter = 4

From that log you would think that it was logging when leds were
blinking, but actually the led-threads might have crashed, and it
would just continue logging anyway. All it's doing is executing
printk's at roughly the same frequency as the LED's are blinking.

This patch rewrites the sample to use a FIFO so that the printk's only
trigger if the LEDs are actually blinking.
