This change capitalizes on newly added support for dynamic
thread stacks and the existing pthread support to provide
an implementation of the ISO C11 `<threads.h>` API.

Leave the malloc partition so that it only contains the heap itself; this
lets the initialization code adjust the address range when configuring the
arena at startup.

Provide a sensible default for the POSIX architecture,
as now it is possible to build with it.

This matches the size that would be used with the newlib_nano configuration
and allows several tests to complete which would otherwise fail due to
insufficient heap space.

When using the common malloc implementation on systems not using the
minimal C library, allocate a reasonable default malloc heap according to
the following rules (adopted from the Picolibc heap size defaults):
* When an MMU is available, allocate 16kB.
* When USERSPACE is enabled for a device with an MPU require PoT alignment,
allocate 1024 bytes
* Otherwise, use all available memory.

Move the abort implementation into common so its shared among the
libc. As part of this start using the common abort on newlib.

Move the strnlen implementation into common so its available to any
libc that may not implement strnlen.

This will (eventually) permit use of a common malloc implementation with
other C libraries, reducing the amount of Zephyr-specific code required
to support each C library.

Introduce a place to share implementations of libc functions that
are needed by different libc versions. Place time() in this common
location so it can be shared when building for either minimal libc or
armclang libc.
