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.

posix: timers: deprecate CONFIG_POSIX_CLOCK and TIMER The POSIX_CLOCK option does not correspond to any standard option. It was used to active features of several distinct POSIX Options and Option Groups, which complicated API and application configuration as a result. POSIX_CLOCK is being deprecated in order to ensure that Zephyr's POSIX Kconfig variables correspond to those defined in the specification, as of IEEE 1003.1-2017. Additionally, CONFIG_TIMER is being deprecated because it does not match the corresponding POSIX Option (_POSIX_TIMERS). With this deprecation, we introduce the following Kconfig options that map directly to standard POSIX Option Groups by simply removing "CONFIG_": * CONFIG_POSIX_TIMERS Similarly, we introduce the following Kconfig options that map directly to standard POSIX Options by simply removing "CONFIG": * CONFIG_POSIX_CLOCK_SELECTION * CONFIG_POSIX_CPUTIME * CONFIG_POSIX_DELAYTIMER_MAX * CONFIG_POSIX_MONOTONIC_CLOCK * CONFIG_POSIX_TIMEOUTS * CONFIG_POSIX_TIMER_MAX In order to maintain parity with the current feature set, we introduce the following Kconfig options that map directly to standard POSIX Option Groups by simply removing "CONFIG_": * CONFIG_POSIX_MULTI_PROCESS - sleep() Similarly, in order to maintain parity with the current feature set, we introduce the following additional Kconfig options that map directly to standard POSIX Options by simply removing "CONFIG": * CONFIG_XSI_SINGLE_PROCESS - gettimeofday() Signed-off-by: Chris Friedt <cfriedt@tenstorrent.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.
