- mpsc_pbuf_get_max_utilization()

It was possible that allocation was continuously attempting to find
space. It could happen if allocation interrupted consuming a packet
(which is marked as busy) and there is not enough space to allocate
requested packet but there would be if busy packet was freed.
Algorithm in that case was continuously going through the buffer
in search for packets that can be dropped to find space for the
new packet.

Mostly a revert of commit b1def7145f ("arch: deprecate `_current`").
This commit was part of PR #80716 whose initial purpose was about providing
an architecture specific optimization for _current. The actual deprecation
was sneaked in later on without proper discussion.
The Zephyr core always used _current before and that was fine. It is quite
prevalent as well and the alternative is proving rather verbose.
Furthermore, as a concept, the "current thread" is not something that is
necessarily architecture specific. Therefore the primary abstraction
should not carry the arch_ prefix.
Hence this revert.

Check if the spinlock is held before attempting to wait by
taking the semaphore, as that would cause a context switch which
isn't allowed and will trigger an assertion error when
`CONFIG_SPIN_VALIDATE` is enabled.
Logging in spinlock-held context when the log buffer is full can lead
to an infinite assertion error loop, as the logging subsys attempts to
allocate buffer when there's none available, it will try to wait for
one and thus triggers the assertion error, the error message will be
printed through the logging sybsys but there's no buffer available,
so it will try to wait for one and triggers another assertion error..
This loop just goes on and on forever, and nothing gets printed to
the terminal.
Added a test to validate the fix.

Previously, if a file object is was re-used, it could
inherit the offset field of the previously closed file object,
making reading from the beginning of the file impossible
until the offset was manually zero'ed.
The offset should *always* be zero when a file is ready to be
used.
The issue really only presents itself when implementing a
vtable backend.

The `zvfs_finalize_typed_fd()` function notifies some backends
via `ioctl()` with `ZFD_IOCTL_SET_LOCK`. However, support for
this method and functionality is optional.
In backends that do not support locking, this benign failure can
set `errno` to 95 (`EOPNOTSUPP`) in many circumstances where a
change in `errno` (indicating some kind of failure) is not
appropriate.
Prevent errno poisoning by backing-up and restoring `errno`.

When the PRESTART thread state was removed, this changed the semantics
of k_thread_start() when thread was created with a K_FOREVER timeout,
suspended and then started with k_thread_start().
This sequence is used in p4wq to implement K_P4WQ_DELAYED_START
(which again is needed by K_P4WQ_USER_CPU_MASK).
With PRESTART removed, the following sequence:
z_mark_thread_as_not_suspended(thread);
k_thread_start(thread);
.. no longer starts the thread. As a result, p4wq users like SOF
multicore configurations, hit errors as p4wq threads never start.
Fix the implementation by removing the calls to change thread
suspended state explicitly, but rather rely on the new
k_thread_create() and k_thread_start() semantics.
