This commit adds names to Kconfig choice sysmbols. This allows for their
selection from Kconfig, e.g.:
choice TRACING_FORMAT_CHOICE
default TRACING_TEST if CONFIG_FOO
default TRACING_CTF if CONFIG_BAR

When k_heap_alloc() is expressed in terms of k_heap_aligned_alloc()
it invokes a longer aligned allocation code path with an extra runtime
overhead even though no alignment is necessary.
Let's reference and invoke the aligned allocation code path only when an
actual aligned allocation is requested. This opens the possibility for
the linker to garbage-collect the aligning code otherwise.

Add new tracing API which is called when core is exiting from idle.
Current implementation is using it to track CPU load. Implementation
in tracing_none is now weak so it can be used if given backend does
not support new API call.
When CONFIG_CPU_LOAD is enabled then sys_trace_idle also calls a
hook which stores the timing information when CPU entered idle.

Add support for a "named event" trace. This trace is intentionally not
used by the system. The purpose of this trace is to allow driver or
application developers to quickly add tracing for events for debug
purposes, and to provide an example of how tracing subsystems can be
extended with additional trace identifiers.

k_pipe_put_* functions should take const void* data
instead of void* data. This can lead to warnings at the
the -Werror=discarded-qualifiers compiler flag, because the
the input will be const void* and the parameter will be void*.
Fix it by replacing void* data with “const void* data”.

Move the implementation of zsock_poll to zvfs_poll. This allows
other types of file descriptors to also make use of poll()
functionality even when the network subsystem is not enabled.
Additionally, it partially removes a dependency cycle between
posix and networking by moving functionality into a mutual
dependency.

Fixes the systemview tracing backend for soc families, such as max32,
that don't subdivide into soc series and therefore don't define
CONFIG_SOC_SERIES. Use CONFIG_SOC_FAMILY instead in the system
description since it should always be defined.

TX time tracing tells how long it took from network packet
creation to when the stack got rid of it.
So the network stack allocates net packet, this is the
start time. The end time is when the packet is fully processed (sent)
by the network device driver.

RX time tracing tells how long it took from network packet
creation to when the stack got rid of it.
So the network device driver allocates net packet, this is the
start time. The end time is when the packet is fully processed.
Currently the limitation is that the RX time duration is used
for network packets that are tied to an open socket.

I am using the tracing module using the RAM backend on a system with
limited RAM & a buffer that can only store 300ms of tracing data. Current
tracing module starts recording during boot-up & we run out of memory prior
to executing code we actually want to trace.
By reseting buffer metadata here, I can call init() at an arbitrary point
of program execution & the tracing module will reset & start tracing.
I tested on E2E on an ARM M-class MCU by calling init & then reading
buffered tracing data via GDB

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.

Modify the signature of the k_mem_slab_free() function with a new one,
replacing the old void **mem with void *mem as a parameter.
The following function:
void k_mem_slab_free(struct k_mem_slab *slab, void **mem);
has the wrong signature. mem is only used as a regular pointer, so there
is no need to use a double-pointer. The correct signature should be:
void k_mem_slab_free(struct k_mem_slab *slab, void *mem);
The issue with the current signature, although functional, is that it is
extremely confusing. I myself, a veteran Zephyr developer, was confused
by this parameter when looking at it recently.
All in-tree uses of the function have been adapted.
Fixes#61888.
