posix: split supported features into separate Kconfig files This change is setting up for switching over to proper POSIX option requirements, feature test macros, and a dependency structure that is reflective of the standard. Signed-off-by: Christopher Friedt <cfriedt@meta.com>

posix: deprecate SEM_VALUE_MAX and SEM_NAMELEN_MAX This change deprecates CONFIG_SEM_VALUE_MAX in favour of CONFIG_POSIX_SEM_VALUE_MAX which maps directly to _POSIX_SEM_VALUE_MAX. Additionally, we add the Kconfig option CONFIG_POSIX_SEMAPHORES which maps directly to the POSIX Option _POSIX_SEMAPHORES. For consistence, deprecate CONFIG_SEM_NAMELEN_MAX in favour of CONFIG_POSIX_SEM_NAMELEN_MAX. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>

posix: separate shell utilities and posix api implementation Previously, the POSIX shell utilities were intermixed with the POSIX API implementation. The POSIX shell utilities only depend on the public POSIX API, so it makes sense to keep them in a separate subdirectory. Signed-off-by: Christopher Friedt <cfriedt@meta.com>
