For SIGEV_SIGNAL, the function zephyr_timer_wrapper() is the handler
between kernel and posix layer.
Here, for one-time timer, reload is equal to 0 and function returns.
As a consequence, handler function was never called.

Move the implementation of zsock_select() to zvfs_select(). This
allows other types of file descriptors to also make use of
select() 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.

Add pread() and pwrite() implementations, which are nearly
identical to read() and write() but differ in that they do not
update the file-descriptor offset and instead read from a
specific file offset.

The POSIX_DEVICE_IO Option Group requires a number of c89
functions mainly from stdio.h .
Namely,
clearerr(), fclose(), feof(), ferror(), fflush(), fetc(),
fgets(), fprintf(), fputc(), fputs(), fread(), freopen(),
fscanf(), fwrite(), getc(), getchar(), gets(), perror(),
printf(), putc(), putchar(), puts(), scanf(), setbuf(),
setvbuf(), ungetc(), vfprintf(), vfscanf(), vfprintf(), and
vscanf().
Additionally, symbols stdin, stdout, and stderr should be
provided.
These should be provided by any conformant C library
(not by the POSIX API).

Implemented the following:
- `asctime_r()`
- `asctime()`
- `localtime()`
- `localtime_r()`
- `ctime()`
- `ctime_r()`
Specifically:
- the implementation of `localtime()` & `localtime_r()` simply
wraps around the gmtime() & gmtime_r() functions, the
results are always expressed as UTC.
- `ctime()` is equivalent to `asctime(localtime(clock))`, it
inherits the limitation of `localtime()` as well, which only
supports UTC results currently.
Added tests for these newly implemented functions.

__z_clock_nanosleep function was getting current time in cycles, via
k_cycle_get_32(), to perform its time calculations. However, when calling
k_sleep() to actually sleep, times are measured in ticks.
This causes a problem when there's a big skew between the uptime
measured in cycles vs uptime measured in ticks: in some platforms, the
system clock maybe up for a long time already when Zephyr starts
counting ticks, for instance, while downloading an image via PXE. In
this case, the calculations done inside __z_clock_nanosleep end up
measuring a much bigger current time than expected, thus sleeping too
much, basically all the time since system clock initialization.
This patch fixes that by avoiding the cycle trip: stick to ticks,
instead. They start counting from Zephyr initialization instead, which
is the expected uptime.
Fixes#69608
