SYS_INIT and DEVICE_DT_DEFINE (and friends).

Tracing with sysview is missing both
sys_port_trace_k_thread_abort_enter()/_exit() which exist on
other tracing backends. So add them.

SEGGER_SYSVIEW_RecordU32 function takes only two parameters,
SEGGER_SYSVIEW_RecordU32x2 should be used instead.

Add a delay parameter to asynchronous device runtim put. This allows
to delay the put operation what is useful to avoid multiple states
transitions.

Fixes several minor display errors in the Segger SystemView output:
* Off-by-one error in some trace ids.
* Add missing syscall trace id.
* Displays easier to read syscall function names.
* Fixes syntax error in k_timer_start output.

Adds event tracing to sysview. This will allow the event related
tracing symbols to be found when CONFIG_SEGGER_SYSTEMVIEW is
enabled.

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

Adds two routines to flush pipe objects:
k_pipe_flush()
- This routine flushes the entire pipe. That includes both
the pipe's buffer and all pended writers. It is equivalent
to reading everything into a giant temporary buffer which
is then discarded.
k_pipe_buffer_flush()
- This routine flushes only the pipe's buffer (if it exists).
It is equivalent to reading a maximum of "buffer size" bytes
into a temporary buffer which is then discarded.

Added heap reference parameter to k_free tracing
hook to allow tracing of the pointer which was
passed as a parameter to a k_free call.
As part of this update the defines
(for this hook) in the various tracing formats
was also updated.

System PM tracing was broken for SEGGER SystemView, and was missing

When generating syscall wrappers, call a tracing macro with the id,
name, and all parameters of the syscall as params when entering and
leaving the syscall. This can be disabled in certain call sites
by defining DISABLE_SYSCALL_TRACING which is useful for certain
tracing implementations which require syscalls themselves to work.
Notably some syscalls *cannot* be automatically traced this way and
headers where exclusions are set are in the gen_syscall.py as notracing.
Includes a systemview and test format implementation.
Tested with systemview, usb, and uart backends with the string
formatter using the tracing sample app.
Debugging the trace wrapper can be aided by setting the TRACE_DIAGNOSTIC
env var and rebuilding from scratch, a warning is issued for every
instance a syscall is traced.
Automatically generating a name mapping for SYSVIEW_Zephyr.txt is a
future item as is documenting how to capture and use the tracing data
generated.

what we had, align with what the tools provides and expand hooks to
support additional APIs. We now cover most kernel APIs.
