If GPIO tracing is enabled, then the system will track
various GPIO pin events.

Add usage example for sys_trace_user_event, to demonstrate how users
could add tracing functionality to their application.

The original idea of z_current_get() was to be the counterpart
of k_current_get() when thread local variable for current has
not been initialized if TLS is enabled, otherwise they are
the same function. Now since z_current_get() is being used
outside of core kernel, rename it under kernel namespace so
other subsystem can conceptually use them too.

Let's just let the user implementation to its things, like
checking, locking and stuff.
The tracing_user.c now just acts as a glue.
Moved previous implementation to its sample, and cleaned up
headers.

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.

samples should not use CONFIG_TEST_EXTRA_STACK_SIZE, instead, they
should set the recommended stack size directly.

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
import re
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)
```

For tracing_user, the sys_trace_isr_enter() & sys_trace_isr_exit()
block any nest interrupts & most SMP interrupts for the user. It is
hard to analyze the IRQ preemption(e.g., each IRQ counter and execution
time). This commit adds ISR nest level for each CPU to the user instead
of blocking user call back when nest interrupts.

The user tracing backend allows one to implement weak symbols to perform
user specific tracing, e.g gpio toggling or spi transactions. This adds
a qemu sample that just does a simple printk for each of the traced
functions, but could be changed to do whatever function the user
desires.

Add support for new tracing macros in test backend. Move header from
sample into the subsystem and make it available for general testing with
any application.

Instead if printing the line number, output the context (thread,
semaphore, mutex, ..) and the ID of the event where applicable.

usb_enable() must be called by the application.
The application may want to register usb_dc_status_callback
and trace usb status codes (usb_dc_status_code).

This is more a sample than a test, so put it under samples with the goal
of having dedicated tracing tests in the future under tests.
