POSIX_THREAD_SAFE_FUNCTIONS already selects POSIX_C_LANG_SUPPORT_R and
POSIX_C_LANG_SUPPORT_R alread selects all of the COMMON_LIBC_*_R values.
That makes the 'default y if POSIX_THREAD_SAFE_FUNCTIONS' clauses in these

NATIVE_APPlICATION (old native_posix) does not support bulding with the
any other library than the host libC (EXTERNAL_LIBC).
MINIMAL_LIBC_SUPPORTED defaulted to y always, and instead the depends
was set in the MINIMAL_LIBC choice.
This lead to the right library selected, but an incorrectly set
MINIMAL_LIBC_SUPPORTED.
Many tests filter based on MINIMAL_LIBC_SUPPORTED, so they were
not filtered out appropriately.
Let's place the depends in the right place to avoid this problem.
Also remove a redundant depends on for PICOLIBC and NEWLIB_LIBC
which already have the dependency in their respective _SUPPORTED
option.

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.

Implement the selection of the picolibc source in a Kconfig
choice as they are mutually exclusive.
The following table represents the possible choices, where 'X'
means that `PICOLIBC_SUPPORTED=n` and is guarded in the parent
level as `PICOLIBC=n`, so we do not need to care.
Module Toolchain C++ | Choice
0 0 0 | X
0 0 1 | X
0 1 0 | Toolchain only
0 1 1 | Toolchain only
1 0 0 | Module only
1 0 1 | X
1 1 0 | Toolchain/Module
1 1 1 | Toolchain only
The current implementation favors `PICOLIBC_USE_TOOLCHAIN` over
`PICOLIBC_USE_MODULE` whenever possible, that preference is
maintained in this implementation as well - the TOOLCHAIN
source will be the default choice when the toolchain supports
it or when the C++ is enabled. Otherwise, fallback to MODULE.

Currently, json array macros are passing the outer "container" struct
to the Z_JSON_ELEMENT_DESCR macro, causing the alignment to be calculated
from the outer struct which may be incorrect. Fix this by using the
biggest shift from the nested objects to calculate the alignment as the
struct size is calculated based on the biggest alignment of it's members.

Currently, `PICOLIBC_SUPPORTED` could be enabled even when
neither the toolchain has picolibc nor the picolibc module is
present, this can be the case when Zephyr is built with
external toolchain (non-Zephyr SDK) + external build system
where PICOLIBC module doesn't exist.
Fix this by having `PICOLIBC_SUPPORTED` depends on either
toolchain OR module, while taking the libc++ into
consideration.
Here's the full logic table of when the PICOLIBC should
be marked as supported.
libc++ TOOLCHAIN MODULE PICOLIBC_SUPPORTED
