armclang: ARM Compiler C library support Support for ARM Compiler C library. This commit add support for the ARM Compiler C libary in: - Kconfig - libc/armstdc A new Kconfig symbol is added to allow a toolchain to specify if they support linking with the minimal C library. Also the CMake variable `TOOLCHAIN_HAS_NEWLIB` is exported to Kconfig so that CONFIG_NEWLIB_LIBS can only be enabled if the toolchain has newlib. The armclang toolchain selects the CMake scatter file generator and disables support for the LD linker template which is not supported by armlink. For the ARM Compiler C library, a corresponding lib/libc/armstc/ folder with a minimal implementation to work with the ARM Compiler C library is added.

libc: Move strnlen into common Move the strnlen implementation into common so its available to any libc that may not implement strnlen. Signed-off-by: Kumar Gala <kumar.gala@intel.com>

libc: share time() between minimal libc and armclang libc 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. Signed-off-by: Kumar Gala <kumar.gala@intel.com>

Use the full Arm Compiler runtime libraries.
A reduced Zephyr minimal libc will be used for library functionality
not provided by ARM Compiler standard libraries.
